Which sealant

[Ralph S3]

Hi All,

One more question re my top end engine rebuild. I noticed when dismantling the engine that at some time in the distant past the inlet manifold, fuel rail and plenum had been removed and when reassembled the mechanic had used what looks like liberal amounts of blue hylomar on all the gaskets. Now, I was always taught not to use any sealant on gaskets unless absolutely necessary. So can I ask advice for what to use (if anything) for the following;

- Intake manifold to heads. In the manual it actually tells you to use sealant in 4 places but doesn't tell you what sort. Burton Power suggested the following unless silicone specified but I'm not convinced a non-hardening compound is the way forward. I would have thought some type of silicone sealant is the best soln. http://www.burtonpower.com/catalogsearch/result/?q...

- fuel rail to inlet manifold
- fuel rail to plenum
- manifold gaskets
- core plugs - never done these before. On t'internet some people suggest sealant, others an oil based paint.

Thanks in advance for any help.
