Yesterday I was putting the head back on my engine after replacing the pistons and headgasket with a much more reputable cp 9:1 piston and cosworth headgasket. My problem is that I didn't notice that the manual says to put silicone around the front chain cover on the HG and at the spots on the side around the chain cover.... is this gonna cause me to leak oil? Or am I safe?

It's going to leak oil. Take it back apart.

It doesn't leak at my builds. I never used silicone.

I wouldn't touch it until it really leaks. Why doing the work before getting problems?

Slows2k

It will leak

to prevent shit from hitting the fan?

If the manual doesnt say to apply hondabond then you shouldnt need to.. only time you need to apply any bond when not stated to do so in the manual is because you damaged the cover while taking it off

Bullshit?

This is your best argue? And you are a site moderator??

I have made 4 S2000 engines. None of them had oil leaks!
My proposal is: save the time and money and do the work of replacing the head gasket only if it leaks (If!). Then he can do the job. If it doesn't leak he saves money and time. Simple as that!

well its only at the front of the head circling the timing chain hole. and the manual does say it..... but ive built quite a few engines (other than f20c) and NONE of them ever required any kind of bond in the front to seal off any oil running through the engine. it just confuses me. i mean, im not scared of doing extra work.... but i dont want to waste more time on a useless tear-down. much less wear out more useful threads in an engine by assembling and reassembling.

but am i understanding correctly that some of you have PERSONALLY built engines without putting the bond around the timing chain well and successfully ran dry?

If you really want to argue credentials I've been a ASE Master tech for the past decade. You put 4 engines together.

I spent the last 12 years at Honda dealer, I currently work for another manufacturers Techline supplying technical support for all North American dealers.

When a manufacturer states to apply a sealant between 3 machined surfaces it's not a joke, they really want the effing oil to stay inside the engine.

Do whatever you want. This guy put 4 engines together without any sealant. Congratulations, you saved 10$. So yes, is the best argument available.

Your post is and you got called out on it. If my screen name said guest it wouldn't change the you posted.
