Finally my 2.7 RS rebuild is complete (warning: many pics and long)

[Fishcop]

So I suppose it would be rude of me to tell you about how pleasant it is working on my 2.7 RS engine in my garage with the warm sunshine streaming in through the window to a point where I consider shutting the blinds and turning on the airconditioner. No wait, I think I'll just open one of the roller doors and try an get a breeze

Ho Hum, very ballsy of you to wear the sandals in the first few pics, especially where you guys are transfering the engine from stand to jack. Looks like you put sneakers on in the later pics though.

Car looks great by the way, excellent writeup too

Yes Amir, we all have our moments of stupidity, I just seem to have more than the next man!

[KTL]

Hey now. I recall a picture of Chuck Moreland removing the A-arm bushings with a torch- in sandals!

We're all guilty of stupidity at one time or another. I recently got a good burn from solder while sweating pipe for my water heater replacement. Where'd I get burnt? Right on the big toe, because I was BAREFOOT. Yeah, i'm a @#$%ing idiot just like anybody else.

Oh yeah, great writeup Tristan.

I wonder why the bearing spun?

I've wondered the same thing. I didn't know much about 911s when I bought this one. If I had I would have been worried about the lower oil pressure once it got warm. My guess is that the PO just did not take care of it and neglected oil changes. The arms that hold up the pressure fed tensioners were VERY badly scored which is a sure sign of dirty oil. At first I thought it was the oil pump but now I can see I have very healthy oil pressure (20 per 1k rpm) so I know the pump is working. The other worry with MFI is that you get fuel in the oil if the MFI seal breaks down. While there is a faint wiff of fuel I think it is due to the extremely rich condition of the pump. That's my next project: getting the mixture correct.

Tristan

Thanks Noah,

Quick update. My rebuild has 1002 miles on it so far. The reason I haven't posted earlier is time related. I've had the car at Road America and Gingerman and I'm going back to RA this weekend. I've had a few gremlins (oil leaks mainly and some electrical) that have kept me from fully participating but I'm hoping that it's all behind me now. I'll post about all the "post-rebuild" stories as I get the time. I think you'll find it equally entertaining.

Tristan - looks great. Good work! As an aside, now I see what Northbrook, Il. looks like. One of our biggest artists lives in your neighborhood.

Inspring stuff. Thanks for the photos and write up!

Great pics... and a great hospital story too!

[CarreraS2]

Great story!

Also, two guys to lift a 911 engine off the stand - you guys are strong/daring.

[Ho Hum 74]

I think daring would be a good way to describe it.

[KTL]

Even more daring (translated: stupid) is trying to put the motor onto the stand with two guys. Been there, done that.

What happened with the Curil-T that you had to replace the flywheel seal? Great story.

[Ho Hum 74]

Neil,

In another episode I'll tell you how after sealing the case the flywheel seal becam a little dynamic and kind of moved around a little. We watched it over the course of a couple of hours and then over the weeks when I put the rest together. I had to keep tapping it back in.

However, after a few track sessions the pressure in the case was sufficient to push out the flywheel seal to a point where it was pressing up against the flywheel and I had a dynamic leak to deal with. Actually I proabably exacerbated the situation by diverting my oil tank vent hose into a container in the engine bay. This was at a track session where I was ingesting some oil into the air filters (probably as a result of slightly over filling). Instead of being chastized by the BMW folks I was running with (they have a thing about Porsches leaking oil) I made a quick catch can. My error here was not venting it sufficiently so some crankcase pressure built up. We live and learn.

This weekend, with the help of another friend and P-car buddy Joe Martinez, we jacked the car up, dropped the engine without removing any oil lines (I have steel flex lines) and electricals (I had to pull a few fuel hoses). I managed to jack up the transmission to a point where I could get at the pressure plate and flywheel bolts. The seal, once removed, was found to be chewed up a little by the flywheel. I cleaned out the area and replaced the seal dry this time and black siliconed the outside where it meets with the case AFTER the seal was in position. Yes, I know this is a little barbaric but it works. Now I have a leak free engine!

Cheers,
Tristan
