Cylinder head to bottom end gasket sealant OK?

[adamt]

is it legit to use crc gasket sealant between the cylinder and bottom end ? that stuff is really good, as i just had a new paper gasket fail me

Some sealants are very good options in certain cases.
But remember, the base gasket is also a form of packing shim that allows a set piston to head chamber clearance.
Alternate sizes are available with some engines, but running just sealant may reduce the clearance to an unacceptable amount.

I'd find out why the genuine paper gasket failed first.And what is CRC gasket sealant?

Think it might be similar to Loctite 515.
I think old dinosaurs like yourself used a slurry mix of pig poo and peat:dodge:

For the few other things... Caterpiller gasket cement. If you can find it.

I wouldn't use silicon on a base gasket unless it was a OE quality....that red crap is useless.For something that really works try Three Bond 1104.I've never seen a genuine base gasket fail unless there was a reason....I've seen my own ones fail of course.

yeah it wasnt oem i dont think, got it off a guy on here, anyway where do i get this Three Bond 1104 ?

I've made base gaskets from pizza box cardboard in the past. They've worked ok.
