I am currently in the process of installing some 107 cams in place of base cams.. I noticed when disassembling the originals from the cam housings, that the gears had some sort of sealer on the end where the cam gear bolts run thru.. Is that a potential leak path or something else?? Certainly did not look like loctite for the bolt, in fact it was more like RTV or something... Anyway, what is everyone else doing when installing cams and the cam bolts? Also, what is the best pre lube to use on the bearing surfaces when assembling? Thanks in advance for any input.

Mark, The cams are 'gun-drilled' all the way through to carry oil from the front journal the journals 2-5. The bolt that retains the cam sprocket and the bolt that hold the rear spacer, are both points for leakage past the threads. I tend to use a little blue hylomar on the threads, but you could use orange silicone (very sparingly) as well. Any commercially available 'Assembly Lube' (or in a pinch, STP oil additive) will provide plenty of protection. The 'book' only suggests dumping a quart of oil on the assembly before bolting on the cam covers. Judson

Dump a quart of oil? That would be pretty funny on the exhaust side! I use Red Line assembly lube but moly is just fine. Kurt

Thanks guys! Now I can move onto figuring out the shim thicknesses I need, etc...

WOW! Exact same question I had about the silcone on the cam cog bolts. I just started putting mine together this morning. I probed the holes and thought the bolt holes had solid bases. If it is "gun drilled," should I clean out the holes with a cleaning rod? What caliber brush is best? Thanks Steve
