YES!
Helped another forum member (OJT) build a 350 a few years ago and he had a chrome timing cover that came with the car/engine. He had a nasty time with it. Appears to be a common problem.

A while back, someone posted to avoid the chrome bolt-ons where leaks might occur....timing chain cover & oil pan.
Guy said they just don't meet metal-metal.

Chrome looks nice on show cars but billet aluminum works better on cars that are actually used.

I think someone said something similar about chrome thermostat housings leaking coolant as well...

Using the correct sealant will prevent any leaking. For the timing cover, I use a coating of Gasgacinch on both sides of the gasket and some RTV red on each end of the front rubber pan gasket. Works everytime. As to the chrome waterneck(thermostat housing), the O-ring type seems to seal better, but a little gasgacinch will help this too.

The thing about chrome is that you should NEVER use silicone on it. (just doesn't like to stick) I recommend 3M 8001 weatherstrip adhesive (a.k.a 'babypoop') on all engine gaskets. Even on chrome, you have to remove it with a wire wheel. It flat-out doesn't leak!

Swell. I'm getting ready to fire up a new engine that has a CHROME 2-piece timing chain cover. (Chrome was the only type Summit had in stock. Otherwise I never would have bought it.)
That's all right. Chasing down leaks is part of the fun, yes?

Re: Chrome is hard to seal...Had a oil leak at the timing chain [CHrome} (The Dude)
could you grind off the chrome, on the lip, to get a metal to metal seal?
looks like i'll go with a moroso oil pan instead of a cheap one... hmm not a bad idea... :jester
And i have chromed valve covers, sounds like a good time for some carbon fiber... well maybe not carbon fiber but something else...

If you ground off the chrome on the lip it would begin to flake off.

Its really a common problem!
Most of the chrome parts are poopiety Taiwanese stuff - very thin and not straight either......
Additionally as mentioned the silicone sealant doesn´t want to stick and therefore a proper seal isn´t given.
I go for original parts and let them chome. Expensive, but worth it!
