Slowest build thread you will ever read.

^ go home zach.

new bolts won't help.

The B6 thermostat is deeper than the relief machined into the block. The proper way to do it is to machine the block to accept the b6 thermostat (what I did). The other way is to sand down the B6 thermostat and use coolant sealant when you bolt it up. The later can be prone to leaks over time (which is why my 2nd built motor... the current one I have... I machined the block).


best of luck!

ahh, I see. The shop that did my motor work recommended sanding down the Tstat when I called them.
I remembered reading about someone machining the block but I didnt realize it was you!
If I choose to machine the block can I just use a dremel? If not what would you recommend?
I may opt for the sanding method, as if anything should go wrong.... tstats are easily replaceable whereas a block is not.

also I think you may have misread my post about the engine mount bracket bolts, (it wasn't worded very well to be honest sorry!)
I'm having trouble on the exhaust manifold side, Trying to bolt the bracket that the engine mount bolts to.
the two top bolts fit in normally but the lower bolt seems to be a smaller size.
Also on the same side I cant get the bolt for the starter to fit into the new block.


My assumption is that these bolt holes lay dormant when the block is bolted to a VW. as the mounting positions are different? and they may have been filled with dirt or sand/rust?

I'm going to try chasing the threads but I was just wondering if there was any information regarding if it required different size bolts for a VW block.

1 step forward 2 steps backwards. Always.
