Re: In need of exhaust manifold for M38

I found this picture of an L-head. The exhaust manifold looks the same as the F-head, doesn't it? If so, that would explain why the F-head manifold wasn't flat but curved upward between the outer and inner ports.





Here's an F-head.

Re: In need of exhaust manifold for M38

They look close but they are different!!! The L-head exhaust has four bolts that run up into the intake manifold! I geuss I'll find out why when I pull this one off. The bolts are a little rusty so I've soaking them with some lube all week. Dont need any more broken bolts!!!
The guy that has the manifold for me lives over by Petit Jean and is suppose to have some cool stuff. Im heading down for Jeremy's wedding next weekend and we are going to head over there. I'll find out when their next rally is going to be and let you know!!! I cant remember if we went in the spring or fall. Thnx for the help though!! Now I know what the F-head looks like(not the ones at work).

Re: In need of exhaust manifold for M38

You have any more Hot Springs wheeling trips scheduled?

If you need parts brought up from the central arkansas area, I travel to Rogers every weekend. At least until we sell or rent out our house in Rogers.

Re: In need of exhaust manifold for M38

I found the answer. The L-head and F-head exhaust manifolds are not the same. Here is a source for a new one though if it comes to that.

Check the mounting surface for flatness before you mount it.

Re: In need of exhaust manifold for M38

I wanted to be in Hot Springs last weekend but had to help with the school carnival for the kids(a nightmare). Jeremy's club had a meet there last weekend!!!! I've got the urge to go but just two buisy. Now the Scrambler has that rear pinion and right axle seal leaking, gotta check that out tomorrow. I can give you Jeremy's number if you want to do some wheeling with some Yota guys!!
I just got done pulling the manifold off the block and still puzzled with why they are connected like that. I geuss I will go out to the shop and pull them apart. Once again thnx for the help and that link and if I plan on doing some wheeling, I'll let you know. If you move back up to Rogers and need a place to work on your rig you can bring it up! I got the big shop cleared out now and have plenty of room!! Ive had the M38, FJ40 and the Scrambler in there and still have some room..
