I got the stuff that eastwood sells, and it went on really well.

Get the Eastwood catalogue, if you are restoring a car, it is required reading. Even if it is to just give you ideas on how to fix stuff, without actually buying stuff from them.

Maybe I'm in the minority, but I HATE seam sealer. In many cases it creates more rot problems than it solves. Yes, it can be done well, but I still say most of it is from the devil. I've had nightmares about removing that crap. I would much rather deal with rust removal, Ospho, <insert your favorite rust killer / preventer / yada here> and a quality rust protective paint (Por15, Hammerite, etc.). Yes, the prep and treatment is critical for a quality result, but man I'm glad to have NO seam sealer.

Hey Jim. Sorry if I went off on a tangent. Where exactly are you wanting to use seam sealer on your 2.0 engine?

Dude, sorry for the semantic confusion. But when I heard "seam sealer" I was thinking of the more common seam sealer used between body panels.

You are talking engine parts, which is a different matter. And now let us address a whole new series of opinions!

Ok, some of my opinions on this...

Pushrod tube seals: Loctite 565 flexible sealant. Rotate the tubes and let them set. I think Jake will back this.

Case halves and jugs? Not sure you need chemical junk there, but I will defer to the engine gurus on those.

Intake runner gaskets? Nothing crazy needed there. I used a cheap solution: Radiator hose pieces that match the dimensions. They are nice and tight. The purists will insist on cloth-covered pieces.

Exhuast rings? If you mean the copper gaskets between the heads and headers/exhuaust pipes/manifolds, then just get them from a local VW supplier. Cost is not an issue.

Best of luck!

ok so for push tubes i need a flexible sealer huh?

i heard that the 6-ers use loctite 574 for the case

for the intake runners i mean where the runner meets the intake port of the head.

i didnt think the exhaust needed sealer, but i had to check, over the course of buying parts for the rebuild i have accumulated 2 sets of copper exhaust gaskets.

thanks for the response

Yes, pushrod tubes, loctite 565 flexible sealant, has Jake's approval.

Again, I don't know about the case. Looking forward to learning from this.

Intake runners to me are the air tubes. If you mean the phenolic blocks, then I look forward to more input from the gurus. My take is they have paper-like gasket material on each side and do NOT need any kind of sealant. If Jake or some other guru pipes in and recommends a sealant then I will be schooled. Otherwise, just clean the surfaces and bolt it up.

The copper exhaust gaskets between the heads and exhaust pipes/headers... just make sure you have only one set (sounds dumb, but many people have dealt with extras in there). No sealant needed there. Just clean and unmolested surfaces.
