Are there any recommended or better than other breathers I should be using? Previously I had only one small breather in one valve cover... After initial warm-up and a few mild passes I had quite a bit of oil coming from valve cover gaskets, and where the intake meets the block, it had spit out the silicone, and also pushed out the not so snug breather I had in the one valve cover.

Its a BBC 468 and should turn about 7k (after a gear change probably).

I know I can go with tall breathers bolted onto each valve cover up towards the front (to avoid oil slosh) I could get breathers with tubes and run hoses to a puke tank or weld bungs into the headers and run a vac-u-pan setup. Considering I just lost my job I'm not looking to spend a fortune, but in the same token know that if its worth doing, its worth doing right, once, the first time.

If your rings are sealing good 1 good breather on each cover will work, but I would put a Vac-U-Pan deal on myself, you can save money and make it yourself, just go to the parts store and get some Mopar breather caps, then go to the local junk yard and get a couple of old GM smog valves, and a couple of 2" pipe nipples from Home Dump, weld the nipples to the headers run some hose and you're done!.. Go to Summit's site and look at the parts, probably make the works for $20!...

Well the removal of the valve covers to install some donated old school 90 degree magnesium showed bigger problems.

It looks like the problem started my previous trip out in september. I had intake manifold gasket fit issues and thought I had taken care of it... apparently not. It looks like water AND gas had gotten into the engine. More water than gas, the water, leaking from the intake crossover appears to have created rust inside the engine which is not good I'm sure...

I purchased thicker intake gaskets to fix that problem, but think I am going to swing it by the machine shop tomorrow also to check intake manifold fit / angle and to take suggestions about the rust.

I'm thinking I'm gunna have to pull the engine and check the mains and a few rods. Hopefully I've caught it before any damage occured, it was ran less than a hour this trip and not very hard... but I know that means about nothing.

So, when you took the intake off did you see traces of water on the gasket??, and where is the gas in the oil coming from??!..
