Did you try using the back side of a fresh razor blade to make sure you scrapped it all off? I had a few stains / marks on my block -- just scraped, scrubbed with SB and then said f-ck it and moved on

 

I used a plastic scraper, lots of WD 40 and a green scotch brite. I used a dull screwdriver to help with carbon on the pistons, but not on the gasket surface. I will try this gently and see if anything changes.

I am being neurotic, but if you look at the picture I posted does that bolthole look OK for install? Or do I need to go over it again?

 

 

 

Yeah, man. Automotive Neurotic over here. I am going with it. I have done the best I can I believe. The bolthole have been brake cleaned, blown out, vacuumed and q-tipped. I don't think there is any way the studs don't seat well.

Aside resurfacing the block I don't thin the surface can get cleaner honestly. I don't think I am going to attempt that.

Good news is that my Fan Controllers temp sensor can fit on an empty bolt at the back of the cylinder head. So that should be a little more accurate.

 

 

 

Reading through the RAVE and my next steps. It says to lubricate the new "Coolant Rail O-Ring" but does not say what to lubricate it with.

Oil? Coolant? Water? Any ideas?

Did some searching, found it should be a silicone lubricant. I do have silicone grease, so I will have to check and see if that will work.

I have lithium grease, so am going to have to source some lube.

After research I am going to get some Plumber's Grease at Home Depot. They have high temp.

 

More dumb questions. Can anyone tell me what these parts are for?
