Project 3.6 RS Thread, Getting the bugs out and oil line leak Options

[Steve]

After 23 years of service out of my 3.2, I decided to buy a used 1995 3.6 from LA Dismantler with 110k miles on it. I paid $25k for the motor, Plus an additional $3k from PMS for conversion parts. Got this motor home and two of the cylinders had bad leak down from the exhaust valves. Lots of goofy issues with 3.6 motors. They have an electric smog pump which clogs the SAI passages in the exhaust valves. Sometimes you can turn the engine over with compressed air through the spark plug openings and use a rubber mallet on the exhaust valves to clear it out. This did not work for me, so I sent my motor out to get a top end overhaul, bigger valves and RS Cams.
This will not be an RS spec motor. RS Spec is 3.8 liters, bigger valves, different injection, etc. My motor is just a 1995 993 motor with one size bigger valves, RS cams and steve wong chip. I asked PMS about the 3.8 slip ins and they said their is very little noticeable difference between the two and not worth it unless your changing the P&C's anyway.

LA Dismantler lessons learned:
-Get a warranty in writing
-Do a leak down at their location before buying the motor.
I did neither and they came up with a ton of excuses not to help me.
This is also true for any wrecking yard. My Euro 3.2 also came from a wrecking yard with no warranty, but that motor was flawless.

This will probably be a very slow progress thread. I still work full time and have a family. I bought this motor two years ago and finally pulled the 3.2 a couple of weeks ago. I sold the 3.2 to the guy that did the top end overhaul on my 3.6. On the 3.2, two of the cylinders had poor leak down, due to weak rings. The motor ran great before I pulled it and all the spark plugs looked the same. So I was very surprised about the leak down results. Besides spending $4500 to PMS three years ago to reseal this engine, it has never been apart. The PMS reseal was due to the normal oil leaks around the cam chain housings and other areas. Who knows how many miles were on it. The guy who bought it said the rings are weak and to spray WD40 in the cylinders. Sure enough it brought the leak down, from 30% down to 3% on one cylinder and from 10% down to 5% on the other. He plans on doing a top end overhaul on it and flipping it or putting it in one of his 914's.

I will add pictures and more info as time goes on.

Steve!!! Geez maybe I should be more active here these past few months! Everything you are dealing with now is exactly what I am dealing with. Getting the engine in the car was the easy part. Trying to figure out the wiring has been a big freaking headache.
Our projects mirror each other except the you going into the top end. I bought the engine from LA Dismantlers with 38k miles in 2015 and paid a fraction of what they go for these days. I wouldn't be able to afford this now.
Unfortunately I am headed to Florida for the winter while the project will have to wait till May 2025 to get it going. I will follow your progress closely in hopes your issues get resolved quickly and it gets me closer next spring ! best of luck to you
