cylinder head

Hello all, got a question for anyone who can help. I already tried a search and couldn't find anything.
I purchased a 92 samurai a month ago. It had a siezed cam. I took a chance on a junk yard head & cam (gasket cost more than the head). I got the thing up & running and it runs great. It runs 65 pounds of oil pressure @ 1800 RPM warm The problem I have is it smokes real bad. When the head was off I inspected the cylinder walls and they looked real good. After I saw the smoke I ran compression and it has 175-180 pounds on all cylinders. #4 spark plug is running wet, 1,2 &3 look real good. I checked for play in the valves and they were about the same as the rest. I know thats not a good check but with that much smoke I would have thought something would be obvious. Can someone fill me in, do these 1.3's run valve guide seals? mine don't have any on either the junkyard head or the one I pulled off. Has anyone had valve guides smoke that bad? This thing gets worse as it gets warmed up. I'd be thankful for any help.

Re: cylinder head

I just replaced a head gasket on a buddies rig and ended up with the same problem. Instead of leaking water out the side of the block, it is now burning oil like CRAZY. I can't figure it out. In my case, I know it isn't the head, it has to be the gasket (I used a Fellpro one too??) or the installation (you either have it in right or backwards right??). Anyway, hopefully someone has some ideas. I am all ears on this one.......

Re: cylinder head

Are you shure you got the head gasket on correctely? There is a hole in the front that lubs the cam and If you put the gasket on upside down you'll wipe the cam. I don't know if it would cause oil burning or not though

Re: cylinder head

I am aware of the hp oil hole and am sure it is in right. The engine has about 20 hours on it and if that was wrong, it would have fried the top end long ago. Its gotta be something else....

Re: cylinder head

Yes, I too have put the head gasket on correctly. with all the hype around about the "oil hole", one would have to be silly to put it on wrong and probably shouldn't be pulling lids off engines. I'm so confused! [img]images/graemlins/grin.gif[/img]

Re: cylinder head

In my experiance its not uncommon for a tight head on an older lower end to blow
the rings out as far as oil consunmption. You can still have decent compression and
burn oil.

However, I would take Sarges sugestion on the PCV, and make sure the hoses feeding
it are clear. The other thing is when you take a yard head, you should at least put
valve seals in it Those little rubber umbreallas (Assuming a zuke uses those, I havent
had to do a zuke head yet, very soon though.) are useless when they get hard.

Re: cylinder head

Yes, the Sami head uses umbrella seals . If it sat for awhile or the pcv is clogged , good chance one or two has blown itself off the valve guide ...
