Well...being that everything appears to be back together 100% except that $#@damn stripped out hole in the side of the oilpan, I sat and thought about how I may get around pulling my oilpan to fix it. I came to the realization that the banjo bolt from the turbo oil line could be welded to the the line and then welded into the hole on the side of the oilpan. A mig weld done correctly should hold up to the 5 bars of pressure that may come through this line, correct? Next time I have to replace my oilpan gasket, I could either unbolt the line from the turbo and drop the pan, or replace the pan, the line, and the banjo bolt. I could have my car towed 3/4 of a mile down the road to the import shop I have been using for some things and have them weld the line on. Are there any clearance issues with fitting a mig welder between the banjo bolt and the sub frame (the only issue I saw) or the top part of the banjo bolt (where the line covers part of where you may need to fit the weld around)? Does this seem like a more practical solution than redoing *everything*, or should I just do it the right way? Let me know guys.

Sounds like sooner or later you're gonna have to do it right, get it over with before you regret it

nickhance

I'm no expert here, but there's no shortcut for doing things right.

If it were me, I'd grudgingly take it all apart and do it again so I know it will hold up and so I know it was done right.

You know Dave and Nickhance or correct, BUT I think that you have found a good solution to your problem. GO FOR IT!

Thaddeus

Yeah ribs, even if welding it fixes your problem short-term, you still have an unknown quantity of metal filings inside the engine. You may be buying big trouble if you just button it up and run.

Ribs,
I don't own a turbo so I am not sure about what I am talking about, so I may be talking out of my ***. But if this banjo bolt goes right into the oilpan which is aluminum unless the banjo bolt is aluminum also you could not weld them together, and even if they were both aluminum they would have to be tig welded together. My guess is the banjo bolt is probably brass and even if it was threaded into some kind of steel boss you still could not just mig weld them together (could be brazed though). Basically what I am getting at is that you would have to have (2) similar metals to weld them together. If it can be done though, probably be a quick fix but like others have have said already there are no short cuts to doing things right. Like what would happen if for some reason you had to get it apart, what then? Besides doing any kind of welding on a car can cause havvok with the electronics, if you do go ahead with it, pull the battery completely out and remove the DME/KLR.


ahhhhh.... just quit procrastinating and pull it apart

TurboTim

You cant weld it. They are two different types of metals. Better think of another solution:^)

Ribs,
There is a shop up in Delaware that knows Porsches of all kinds very well. The owner is a big Porsche guy. They do alot of 944 work and have been doing work on my old 951 for many years. It might be worth a phone call to see if they know of an easier solution.
The name of the shop is European Coach Werkes they are in the yellowpages under auto repair

JB WELD it. <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />
The real way, other than pulling the pan would be to drill and tap the pan with a larger size, then get an adapter(reducer) to go from the banjo bolt to the newly enlarged and tapped hole. If I had a lathe hooked up I would make you the adapter.

good luck

Have you considered Timeserts? or Helicoils. They are used to repair stripped spark plugs and head studs.

If you want to bond them together, go for some of the industrial-strength cyanide-based 3-part epoxies; easily 10x stronger than JB-weld.

Actually, you can weld aluminum to steel. You would use an intermediate material that bonds to both. Ferrari has a stuff called Ferran that is used on the 360 Modena to weld the aluminum body onto the steel frame & chassis.

Hi Ribs

In general, welding two different materials together is probably possible.
This depends on the material composition of the both materials(chemical analysis required).
Results depend largly on the level of experience of the welder.
You will find these guy's with industrial welding specialists only (Not at the frendly next door car shop).
They tend to charge an hourly rate that matches with the skill so you could probably get a new oil pan for the same costs.
The guy would want perfect access and the weld must be visable for him all the way, so the oil pan should be removed anyway.
I think the insert (Timesert) would be the best intermediate solution.
In case you go for an adapter, make sure that there is enough body in the oil pan for the new thread.

Thanks for the replies guys. I called or stopped by that import shop 10 times in the last 2 days and nobody has been there...I think somebody died or something...it can't be good news if your business is shut down for several days. Anyways...I have heard that it is possible to bond aluminum and steel using an intermediate alloy like danno said. I don't know if that shop would be able to do it with their mig welder, but somewhere in this town better be able to. As far as removing the line if I ever have to drop my oilpan again...its easy. There are 2 bolts that hold a flange of sorts to the bottom of the turbo where the line comes out of...it looks just like where the oil pick up tube bolts to the motor. Other options I have considered if it isn't possible to bond the 2 dissimilar metals together is cutting the braided line, clamping it to another line, clamping that line to an aluminum rod, and having the aluminum rod welded into the oilpan. Welding aluminum to aluminum should be cake, correct? Anything thats not going to cost me over $250 to be a semi permanent (meaning nothing that will leak until the next time I have to replace my rod bearings/oil pan gasket so I can fix this whole deal correctly, and $250 is the end of my budget for this car) fix to my problem will make me insanely happy as I fixed the rest of my issues (installed driver's side front SS brakeline, moved my PS resevoir down to its proper placement as per the advise of a board member, and got my upper dipstick tube into the lower dipstick tube as I messed that up when I installed my intake manifold) with the front end and are going to install rear shocks, brake lines, and brake pads tomorrow (torsion bars are going to have to wait until I can have somebody with experience help me). If I ever have to go through this whole deal again, I am definitely going to set aside $600 to buy lindsey racing's detachable sub frame and crossover pipe. The one local exhaust shop I took the crossover pipe to to attempt to get it cut looked at me like I was on crack when I explained the reasoning behind it.

Turbopop...I'm going to call those cats tomorrow up in delaware and ask them what they think of the whole thing. Do they do alignments in house, too? I'm trying to find somewhere I can get all the rest of the work I need done done at.

I know Mater Bates will enjoy this...I had a friend come from out of town tonight, and was trying to have a good time in my little college town I live in. He just got layed off of one of his jobs (his steady job...the company went under...the other job he still has is only when the studio has work, which isn't very often...other than that he is a semi-pro musician, too) so wasn't trying to sit around and watch television...he was trying to drink heavily. Well...he drinks 6 beers while he's at my house waiting for me to eat, get ready, and finish my school work. We go over to my friend's house...he drinks 4 more beers. He is pretty housed at this point, so I suggest we go to the local "meat market" bar where all the drunk ***** go and pulling a POA is about as hard as fishing in a stocking estuary. We go in for 5 minutes, and he isn't feeling it, just as a gaggle of beautiful fake and baked breast implanted "perfect in the eyes of most guys" girls walk in. I try to talk him out of leaving, but he is insistant. Its his night, so I humor him. We go to a more chilled joint...a place called break time...its a sports bar. I haven't drank until this point as I am driving his car. We get a couple of rounds (I had 3 beers the whole night) and play 5 or 6 games of pool...I kick his *** miserably. Well...at this point, my friend (a scrauny 160 pounder) is about 14 or 15 beers deep, and decides to order some shots. I turn them down, but he takes a round with a guy who is friends with a friend of his he met at the bar. He takes 2 more, and the bar tender is hooking them up, making them doubles, not to mention they are a nasty combo shot...liquid cocaines are what they are called...1/3 Jeager, 1/3 rumplemints, and 1/3 goldschlager. So my boy has had 15 or so beers and around 6 shots in a very short few hours. He falls out of the barstool and I tell the bartender I will take him to his car. I take him to his car, and have to have somebody from inside the bar pick his *** off the ground to get him into shotgun. I start driving away, and he speaks giberish to me the whole ride home. Anyways, we get back to my house about 2 minutes later I try to scheme a way to get his *** who can't stand up on his own two feet to get from his car to my house which is all of 20 feet. I spend about 10 minutes trying to talk his incoherent *** into getting out of his car and into my house, and finally give up after he spews a round of insulting words towards me. I get out of his car and tell him "if your pea-body drunk *** can't figure out how to do the two foot shuffle from your car to my house, you can sleep in your car". For some reason, pea-body really pissed him off as he jumps out of his car and attempts to tackle me. My roommate comes outside at this point as everything got kind of loud...he just stood there and made sure everything was koshure. Fighting a skinny drunk as a skunk motherf'er is like fighting your little sister...you don't want to hit them and maim them, but you don't want to get messed up either, so it usually ends up with you (me) pinning the perp (them/little sister) in a semi-painful but unescapable hold. I got my friend locked down in about 20 seconds, and I just stayed there, pressing his arms to the ground until he completely ran out of strength, which took about 5 minutes. I got up after I thought he was cool, and he tried to take my head off with a plastic lawn chair. Another 5 minutes of pinning his *** to the ground, he passed out. Me and my roommate went inside, my roommate went to bed, but I went out 20 minutes later to see if my friend was still out of his mind drunk...I woke him up and he tried peeing on my neigbor's car. I ended up grabbing him and got him inside on the couch. Just because he was an *** and tried taking my head off with a plastic lawn chair, I decided to snap a couple pictures off of, but will protect his privacy and blurr out his face since I'm not pissed at him enough to go all out. Anyways...drunk *** after using all of his energy:

The biggest problem with welding alum. is that it has to be pre heated and heated pretty well.. thus gasket is already bad afterwards and you will have to remove the pan. to fix the gasket.

Ribs,
They do not do alignments at that shop, but... a shop right by the college (Delaware Tire) has always done the alignments on all of my cars, including the Porsches. I've been very happy with them. On the rare occasion that they did not perform to my satisfaction, they corrected or re-adjusted at no cost without argument.
