Bad valve guides?

[zacmustang03]

Hey guys hope this is in the right place . So end of the year my car started to puff smoke under acceleration or upon start up . Was using oil from what I noticed looked to me like it was just blowing it out the exhaust . So I know I should of done a compression test, but I didn't and just took the engine down to the short block this winter . Pistons all look good nothing wrong there . There is a small amount of oil In the lower intake ( my pcv is deleted and the intake hose is plugged off. Looks like it came from one of the cylinders . Here are the pics of the bottom of my heads . What do you guys think? Valve guides? Or something else .

this is the passenger side . Looks good to me

drivers side and the very back driver side looks like it's got a lot of carbon build up on the plug as well .

Place the heads valve side down and pour a little oil over the valves. If you have spots on the floor underneath then they were leaking. If not then you might have blow by. My #5 and #3 cylinders have a bad valve guide and blow smoke periodically on start up. Nothing during driving though. Good luck

Well now that it's all apart I am going to swap them all but I just want to make sure it's nothing else . Looks like that back cylinder might not of been firing by the look of the plug

The amount of oil around the intake valves on the pass side is not Ok. I would guess valve guides as the engine is pulling vacuum while they are moving and the oil is heavy around them.

That was my original thought glad to get a couple confirmations

I think I might have the same problem. I just picked up some DB castings as an upgrade and will be rebuilding those heads instead. I still need to take my car apart to see exactly what's causing the oil on start up. Good luck with your build.

where do you find the DBs? Junk yard aviators? Ebay? I look every now and then but dont see much.

I found a set of DC casting heads on Craigslist for cheap. I would continue to look on ebay and also try CL. It's all about timing and catching a deal before someone else does.

Noob question what does DB casting mean?

cylinder head castings for dohc cars. Google terminator cylinder head castings and you can get some good info on it.

I just remembered that the guy also had a set of DB casting heads; I can post up the CL link and you can contact him and see if you can figure out shipping arrangements?

He's been trying to sell them for a while so offer him $500 for the DB set and see if shipping costs aren't that bad.

Thanks man. Just emailed the company.

Thanks man. Just emailed the company.

Did you hear back from the company? If not, someone else just posted a driver side DC head and a passenger side DB head for sale on CL for $600 shipped.

They're off an aviator so they've never seen boost.

Ya he responded but it was kindof jibberish and then he disappeared.

Thanks for the link!
