what to do about the stuff down by the head studs...

there is oil in the space around the head studs on the passenger side of the engine, and coolant in the space around the head studs on the driver's side of the engine. i got most of it out with canned air, as i don't have access to a compressor.

how worried should i be about this?

other than this, i am ready to start assembling. all the rubber hoses under the intake have been replaced, along with a new silicone hose for the BOV and a silicone connecting piece between the throttle body and the IC tube.

also, i got the spring tensioner off. not bad, if you know where the damn nuts are. had to print the page from the PET.

turns out i have RTE head studs (anyone heard of them?), along with the O-ringed cylinder head.

Naylor, When I replaced my 1987 924S headgasket 12 Feb 07, I had the same deposits by the head studs. I did the same and cleaned the groves out. My surprise came when I vaccumed out the antifreeze paths around the cyl. The far rear cyl antifreeze grove had a small mixture of deposits that looked like ground metal and tar about a sixteenth of an inch deep. All other areas were clean.

Raceware produces a high end stud kit (about $260) for your car with a product code of RTE1011. 100 year guarantee and 24% STRONGER than OEM and are designed re-usable. Will not stretch. My only question is do you still use the same torque sequence or give it an extra nudge?

Good luck,

hey john,

my head studs are the raceware RTE's. the mechanic at motorsport told me to coat the the threads with a moly-sulfide grease thinned with motor oil. torgue in the same sequence, in three stages, 24 lbs, 45, and a final of 67.
