Thanks

 

I just have to ask. Was your car leaving a smoke screen behind it just before teardown? Just kinda curious, I've been thinking of re-ringing my engine because it smokes so bad coming out of a decel. Same kind of story with compression and leakdown. With mine, its definately #2. I see scoring when I looked at it with a fixed borescope, but can't tell how deep they are of course. (not as much scoring as seen in your pictures though). My current smoking engine is only a "temporary" also. I've got the original engine in the process of rebuild. Good luck on yours!

 

Smoke on boost? Oh yeah. I couldn't tell as easily during the day, but at night- absolutey. Not everytime, but frequently enough to notice it. It had a blueish tint, but being night, it was hard to tell for sure.

The oddest thing- I was pressurizing my crankcase, blowing out oil from the back of the balance shafts and the dip stick tube. No clever tricks completely solved that. My undercarriage is well lubed now.

 

For what it's worth, my car has similar scoring on two cylinders and has been running fine (over 300 to the wheels) for over a year.

 

Ae you TRYING to be my personal hero? Cause you may be close...

Did you re-ring when you put yours back together?

 

Correct... on the scoring and pulling the pan.

Fresh rings can cut away some of the minor scuffing and help keep the motor going... at least for a while. Eventually you'll wear out the block, but I think spending a few days and a a few $100 is worth saving $5000.

Also, since you'll be pulling the piston/rod assembly, you can toss in new bearings, check end play on your crank, and check the wrist pin clearances. (worn wrist pins allow scuffing to happen, and ovaled cylinders)

 

Perry,


$155 for a set of rings- that sound about right to you? http://cgi.ebay.com/ebaymotors/ws/eB...tem=2465223842

I get the feeling I could make this job easier on myself if I were to drop the motor, what do you think?

 

I don't recall what I paid... I got them along with a very large order. Call Paragon and see what the list price is.. IIRC, they were not very expensive.

 

Paragon has done right by me in the past:: suspension/gaskets/etc... good suggestion. What about dropping the motor?

 

That song is hilarious casue the licence plate on my 924 was Jethro...

I'd drop it, but that is me. It all depends if you have the equipment and time to do it with.

 

I love that show. And now I'll think Porsche whenever I hear the song...scary!

 

I've got tools, space and skills for it. Time's in shorter supply, but I wonder what's ultimately faster- dropping it and pulling the pan/rods/pistons/cleaning/re-ringing/reassembly in the garage or leaving it in and doing all the dis-assembly/re-assembly on my back...

 

It's faster doing it out... and depending how quick you can get the motor in and out of the car, the whole process might be faster.

 

I'd guess a good solid day to pull the engine... another longer day to put it back in...
