I'm shoulder-deep in engine reassembly for my 92 900S.
The engine is out of the car and off the transmission (transmission was sent out for rebuild). I removed the head to address a confirmed head gasket failure. I have the head back from the machine shop and it's ready to drop back on.
I also removed the timing cover to replace the oil pump O-ring. And since I'm in there I'll replace the Hall sensor. And the timing chain. And the top and bottom chain guides. And the front seal.
But in reading the Bentley for reassembly of the timing cover, it says to NOT use gasket cement on the timing cover gaskets. I must have missed this when I first read up on the job.
No gasket cement for these two gaskets? Makes me a little nervous...
Also, I'm reading the Townsend writeup for head reassembly and he described head-bolt stretching with proper torquing. I bought replacement head bolts just as a precaution but in measuring the old head bolts, they were all practically the same length; three or four are maybe a half-millimeter longer. Is this within tolerance? Or should I just utilize the box of brand-new bolts? I've never used new bolts before on other head jobs (though those were 8-valve engines).
