Reading posts from other first time engine rebuilders there’s a lingering desire to do a second engine at some stage, but how do you do that without owning another car? Well, I’ve found a way. A local Rennlister has put the faith in me to rebuild his 107,000km ex Japan motor while he does a back date on the body.
Yesterday, he delivered the engine to my garage. This will be my Winter (Southern Hemisphere) Project. I’m not sure how much I will document here as it looks relatively straight forward so not worthy of a new thread and this thread is long enough as it is.
Anyway, here are some pics

The car owner, Racoguy, is a skilled creator (check out his home made 3 piece Fuchs and GT3 exhaust) so he will do what he enjoys and I’ll do my part. The engine looks relatively clean as I dismantle it. So far a lot of the oil seems to be from the breather.

Look forward to seeing this. I think you should put it all up in a new diy engine rebuild thread!
I looked racoguys threads up. Looks like a really clever guy. Did he ever finish the wheels?

My part in this build is to provide the base engine rebuild i.e. split the case, change bearings and reseal. It seems to be easy so far. Nothing special to mention so I think I’ll just update occasionally here as there are already enough rebuild threads out there. Day one has me down to the long block.

He appears to have finished the rear wheels so I’d be surprised if he hasn’t done the fronts.

Way above my level of expertise! Keep us updated!
ps: shouldn't you have been spending day one waiting on the Mrs for mothers day

Breakfast by the waterfront at 8:00am, art gallery at 10:00am, home at 12:00, 30 minute drive and into the engine. All bases have been covered.

Power steering bolt tip, I think from Rob.
The camshaft tool is a perfect way to hold the power steering drive wheel still and undo the bolt. No possibility of tweaking the camshaft.

Not so lucky with the pulley bolt. The original bolt is 22mm, but the new version is 18mm. The torque setting is 175 ft/lbs so the preference is a 3/4” socket, however the 22mm 3/4” socket won’t fit with the Porsche tool. The socket is too long and the shoulder hits the tool. I either need to find another socket or alter the tool.
Update: I used the 3/4" to 1/2" adapter and a 1/2" 22mm socket. That gives me the range on the torque wrench and the 1/2" seems to be up to handling 175 ft lb.

My tech says it's always best to hold the camshaft at the same end you are loosening or tightening. He does not like holding at the opposite end, saying that has caused an end to shear off in very rare cases..... Nonetheless. ..

1/2” 22mm socket and the Porsche tool sorted the pulley bolt, then it’s the other special tool to force the pulley off the shaft. It came off with a real cracking noise. The general nose bearing and IMs cover area show some leakage but not bad. .
