Make slowboy not so slow

I noticed quite a bit of buildup on both intake and exhaust valves, but it's weird looking, like it's only built up in certain spots.

Also, when I took off the head, I noticed the headgastket was pretty slimy with grayish oil all over, not sure if it was leaking really bad or if that's just from when I took off the head. Maybe thats why it was burning so much oil, and not the rings? It was on both sides of the gasket too, not just the top. Would a really blown headgasket cause a lot of oil burning or low compression? I know my turbo was burning some oil, but that doesn't explain the low compression.

I'm taking the head to a machine shop tonight after work and hopefully find out if it's ok.

What's a good way to clean up those pistons? wd 40 and a rag?

Hmm that is really weird.. the headgasket should be fairly dry. Maybe that was the issue, but hard to tell.

Do the rings, freshen everything up. Do it right this time and it should be good!

If the head gasket was super blown your engine probably wouldnt have even ran. But if it was leaking, you would get low compression and lots of oil useage. It could also just be from separating the head from the block, thats not the cleanest operation in the world. And WD-40 or just some parts cleaner and a rag will work fine to get most of that out of there, but those carbon deposits might be a tougher challange.

I thought about this for a bit, and decided it was definitely leaking quite a bit. It wasn't just oil, when I took off the head it didn't leak any, and when I turned it upside down a lot of black oil came out as expected. The stuff on both sides of the headgasket was grayish slimy stuff. On the plus side, nothing was caked or coated on either the head or block, both are pretty smooth. Maybe because it's an MLS gasket, because when I took off a stock headgasket on another motor there was stuff stuck everywhere on the block and head.

Not sure if this is a big deal, but 3 or 4 of the 10 headstuds actually came out with the nuts, so maybe they weren't tightened all the way?

Drain your coolant, see if there is any oil in it. Or when you drained oil, was there coolant in it?

[asshanson]

Coolant and oil are both pretty clean. I have a gallon container of the oil i drained, it's been sitting for a few days and there is zero coolant at the top. Also the coolant gallon is pretty green still. So yea I'm not sure what is up.

[Febo]

I woulndt worry about it, I think it was just from seperating the two honestly.

[Kevin 1G Drummer]

The coolant would be at the bottom of the oil. But it would take a couple months to separate like that. Was the oil milky colored at all when you drained it?

[asshanson]

I know oil floats on water, but I could have sworn I mixed a gallon of coolant and black used oil together and within a day all the coolant was on top.

Anyway, got a good amount of progress done tonight. Got the rest of the ABS brake lines out, as well as the control unit in the fender. I also got all the new lines installed and hooked up, that was a pain in the ass. Bendy SS lines would have been a million times easier.

You can see on the bottom corners of the new proportioning valve where the primary/secondary lines from the master cylinder go to, instead of to the ABS control unit. It definitely helped clean up the engine bay a bit, I don't have a bunch of lines running to the front corner and back again. You can also see the new hole I have in the fender.
