Engine intake manifold oil leak

LILCBRA · Jul 8, 2019

Depending on what you're looking to do and how much you're willing to spend, here are some cheap options from Minneapolis Craigslist for you to consider. I dunno if your engine is the original engine to the car or if it's swapped from something else, but some of these may be an upgrade for you.....

Ford 302 Heads

These have been under my workbench for 25 years. Supposedly fairly fresh rebuild by Gopher when I got them. E-mail with phone number.

Ford 302 heads

New lower price! A pair of complete Ford 302 heads. Unsure of the year.

minneapolis.craigslist.org

I'm sure these wouldn't gain you much:

Ford 302 heads

D80e heads off a running ford 302. Needs to be cleaned $40

minneapolis.craigslist.org

And here's some with a little higher price tag, but most likely would bump your compression:

Cylinder Heads and Covers for 289_1965-1966 Mustang

Cylinder Heads for a 289 non-HIPO 1965-1966 Mustang. May need to be rebuilt. Head covers included. Were sandblasted and repainted Ford blue to match the heads - there is tape over the intake hose...

OR..... If you were so inclined, there is a 96 5.0L Explorer at U Pull R Parts in Mt Bethel listed online. Their pricelist online says that the complete engine would run you around $180-190. With that you'd get arguably the best production Windsor heads. With some parts swapping from your old engine, you could have that running pretty quickly and I'm sure you'd see a performance improvement even if you retained the stock Explorer camshaft. If you want more performance, you'd have a decent base to start with.....

Yes, I'm bored tonight!!! Lol

It's clear there is a problem. But could a bad valve cause the Intake manifold gasket to blow out?

Valve no, head gasket yes.

Thank you for the voice of clarity. I'll study up on this and get back. Have some things to take care of today.

If It's just the heads or a head gasket; I think I'll take some advice from you and look these up.

Well that took WAAYYY too long. Needless to say here is the leak-down test on #8.

I'm hard of hearing but I think I could hear it hissing at the back of the manifold. no bubbles in the antifreeze. I couldn't hear anything at the oil fill nor the carb.

Thoughts please.
Thank you,
Enzio

If the air is coming out where the gasket blew out, it's either a head gasket or a defect in the block or head (such as warpage or a crack). You can verify that it's pushing combustion gasses out to the crankcase by connecting an air hose to that cylinder again and listening/feeling for air at the dipstick tube, oil cap, or breather.

You can also spray some glass cleaner or soapy water at the area you suspect while supplying air to that cylinder for a visual indication.

Hopefully it's just a head gasket.

Enzio · Jul 10, 2019

I'll let you know. what kind of pressure should i use?

Enzio · Jul 10, 2019

No bubbles. It was pumping the air through there like crazy. I think when I shut off the compressor at it's peak pressure i could hear the air from the exhaust. So, that tells me the valve is bad and it doesn't solve the manifold gasket blow out unless I didn't do it right in the first place.

Unless you tell me different the head needs to come off.

What would be the best set up for heads and I'd even entertain a camshaft if i can make it happen without pulling the engine?

Enzio · Jul 10, 2019

Heads need to fit the headers. I still have the receipt and they were blackjacks listed for GT40 heads. A kit would be nice.
I am going fishing again starting tomorrow afternoon so I have some time to ponder this situation. I'd like to have up to 300HP when done.

This is a good question I've contemplated too. Can you swap cam with block on the mounts?

Enzio said:

Always the right choice

Enzio · Jul 10, 2019

I think so. I'll replace the water-pump which is almost 30 years old so that'll have to go. (remember water pump envy) So the radiator will need to come out. small thing to take the grill out should be room to put a cam in there. Others here should be able to tell us because I don't know.

Fishing is something that I've put off due to life. Now's the time for me to catch up...

Did you make sure the valves were closed before putting the air in it?

Enzio · Jul 10, 2019

I'll test it one more time in the morning. I tried with a pencil to bring it to TDC. If I went a little to far I'll check again. I covered the intake with dove and water mix. Again, I'm hard of hearing. especially high frequency. I'll ask for help tomorrow and let you know. Thank you for your help.

Enzio · Jul 11, 2019

couldn't find anyone to help out. most people are working. there is definitely air from the exhaust. I can't tell if there is any leakage at the manifold end seal. Now, I'm going to check one more thing when i get back from fishing which is to see if I have the #8 exhaust valve too tight and therefore not closing. I don't know if that's possible or not. But I will check.
thank you for all the help. i'll check in this weekend when i have a moment. where i'm going has signal.

The best setup for heads depends on what you want from the engine and how much you're willing so spend. There are a lot of options out there! A set of GT40 heads from a 96-97 Explorer are pretty cheap and are a definite upgrade over stock. I'm sure you could reach the 300 hp mark with them. But they're bottom of the barrel in some respects compared to any kind of aftermarket head. Not that they're a bad head, it's just that there are a lot of aftermarket options that perform better.

I'm on my work computer right now, but when I have time later I have a couple pages bookmarked for some cheaper aluminum heads that I'm considering for my 87 GT convertible project at some point. One set is from Speedway, the other I can't remember off hand but they're basically Pro Comps if I remember correctly. There are horror stories with them, so if you were to decide to go that route the consensus is to have a reputable shop go through them with a fine tooth comb before installing them. The Speedway heads were in a comparison article in a magazine a while back. I can't remember which magazine it was, I think maybe it was Mustang Monthly? I'm probably wrong, but they performed on the lower end of the spectrum yet comparable to some higher end, name brand heads like Trick Flow and Edelbrock but for less money. Like I said, if I have time in a while I'll post the links as I have them bookmarked on my laptop.

And yes, you can swap the cam in the car. Just remove the radiator and grill and go through the opening. It's not quite as easy as it is with the engine on a stand, but it's definitely doable.

Rained out from fishing till this evening.
Been thinking about the Cobra II and what I'm going to do. My lack of automotive knowledge makes me hesitant to get into something that I'm afraid I'll regret. So I'm thinking of getting 5.0 roller with cam and heads. Is that crazy?
I'd try to convert my old 69 block to roller but am unsure if I have the ability to do it and don't know if it's even possible or recommended.

There are retrofit lifters for non-roller blocks.

If you get a roller block, you'll need to have your flywheel re-balanced by a machine shop.
