Main cap bolts get sealant?
When I removed the 4 bolt main caps a few months ago they were coated in some type of goop that looked like black RTV.
In the assembly manuals I've been reading there is no mention of using any type of selant on the main cap bolts??? :confused: :confused:
Is there a reason the factory used sealant on the bolts??? Should I use any sealant on the cap bolts? :confused: It doesn't make any sense to me.
Thanks
Len

no, no sealant, but a light coat of oil, and if you are using ARP bolts, they supply you with moly. The oil prevents the bolts from galling and binding while getting torqued.....does that sound right?
anyway...no sealant, but sealant on the head bolts that go into the water passages.

Just a qualifier. GM recommends using a sealing compound on the back cap when installing the rear crankshaft seal. That is my job tomorrow. Will use Permatex 2. For the rest, no.

Paul---I saw the reference to sealant in the manual & the rear main. You are correct.
