Okay. It's a 87 944 2.5 with 200,089 miles on it. Let me see. There is no smoking of any sort. Very, very slight ticking when it is just idling.Then, I would say it turns into a loud pecking sound as more gas is applied. I just got the car three weeks ago, and I was told that it had what sounded to be a top end noise. So, I got it home, did some general checks, and the oil smelled like gas. I changed the oil in which had small metal shavings on my oil plug magnet{not good}.The back sparkplug wire{near the firewall} can be removed and it keeps the same idle and it is getting fire. Plus, that same plug had some sut on it. So I have taken out all of the injectors, cleaned them, and that has taken care of part of the npise. I think that a bad injector is possibly what lead to the fuel smell in my oil. (Maybe the injector was stuck or just a weak and not able to hold back the pressure ~if that is possible~). I have checked my compression. The front cyl. at the grill compression is as follows:#1= 170. #2.=170 #3.=135 and #4.= 180. That being said, #3 is off from what I've been told. That's it. I hope I have xplained myself in a manner that is understandable. Thanks for your post. Calls are welcome or I can call you. My number is 606-524-2287.

Have you tried running a compression test? If a lifter or the valve train is bad, then you should see that easily with a compression test (e.g. little/no compression in that cylinder). It does sound like that may be your problem, since the cylinder is dead and you are hearing noises there.

 

OK Tom thanks i will check into that can that be done at a regular Auto Repair there is know one within 100 miles from that i have found so far that will even look at it but should they be able to check for bad compression?

 

How hard is a lifter or the valve train to fix. should my local repair guy be able fix such a problem as that. He is very good at Chevy,ford ,dodge toyota and such and honest

 

Well, this engine is really no different from any other engine... I rebuilt mine as a complete novice... just so long as there is a good manual... checking compression is easy as hell. just remove the spark plug, and put the tester in it's place.

However, before you throw a new valve train at it, diagnose it! go to Auto zone, pick up a compression tester... if you have good compression, no valve problems.

I'm guessing spark... so check the cap and rotor, the plug, and the plug wires.

best of luck!

 

IHave a new coil,rotor button,cap and wire all are new thanks this is so much help Bro

 

Compression testers are available at virtually all local auto parts place and are easy to use. And also, yes, any reasonably competent mechanic can run a compression check for you. If by chance you do have a bad lifter/valve, it might be worth taking it to a porsche-friendly wrench. It's not rocket science, but the local guy won't have the belt tensioning tool among other things...

Good suggestion about spark. Have you checked to see if that plug wire has spark -- no tools needed -- just hold it (with well insulated hands) against the cam tower while the car is running and see if it arcs. Cap, rotor, or wire could be bad if no arc. EDIT: typed too soon -- sounds like you are covered there. Have you checked to see if the plug is physically damaged?

 

no prob. so, new ignition stuff eh? well, valvetrains don't usually just break...so, it may be fuel. try running the car for a bit, then immediately remove the spark plug, and see if you smell fuel... if you do, then there is a compression issue...

 

It for sure has spark from the wire. just not pulled the plug out to check and see how it looks. as crazy and simple as that is

 

well check it out bud! with Rennlist, anything can get done

 

Heys guys thanks. Have just owned my First Porsche for less than 2weeks. I live in the Appalachian Part of Ky not many Porsches at all in my area. Sorry for so many questions. I'm just so excited to get it on the road. Yes i will take my time try to do it all right as i can

 

Plug dry with a dark dusting and my oil stick smells like Gas??

 

Strong smell

 

So that suggest your injector is firing into the cylinder, but is not burning away like it should. You don't want to drive with gas in the oil -- bad for your bores, bearings, etc., and dangerous. Time for that compression test. You can also try swithing the plug and injector from another cylinder to see if the problem moves to the other cylinder -- to see if its a bad plug or injector.

 

ok i went out and got a new plug an hour ago put it in same problem
