Water in the oil

[Massimo]

I had a problem with overheating back in the fall when i parked the car for the winter. I was loosing coolant but it was internally because i never found and on the ground under the car. i had checked the oil but i never changed it and i didnt find any water in it. I finally had some time today to start checking into why it was over heating. i pulled the dipstick and sure enough it was milky. So now i know i have an internal leak but i dont know where. First thought was i might have had a small hole somewhere around the water pump because that broke last year and i replaced it. second thought was head gasket. any advice on where i should look is greatly appreciated.

by the sounds of it and speaking from experience, thats a head gasket. I know on my 260 we ad to replace the head because it was common for them to crack. how ever lucky for you they are asy to do.

[Massimo]

Sounds like i will be replacing the head gasket then. i had a feeling that would be the problem with it.

It could be just the gasket or a cracked head as mentioned above. I had a fan belt snap and in no time at all the car overheated and the head cracked. Also a 260.

Yes, you will be replacing a head gasket for sure but... You should check that head and make sure it didn't warp during the overheating. As long as you have it apart, you should do the valves and replace your timing chain, water pump... Ahh the infectious "while you're in there disease".

yes i was just talking about that tonight i was thinking about pulling the engine but i then its like while you have it out... but now i can have a reason to fix a few other things like a broken bolt on the exhaust manifold and replacing that gasket. im hoping to make this a quick fix with funds and time little tight right now i just want to get it back on the road. but i will deff check into a new timing chain, valves, and checking over the rest of the internals while i have it apart. at least the the water pump is already new.

Is Furggie's (spl?) Blue Note still just off the square? How about the Boston Spaghetti House - is it still in the flats? Do the Moyer Brothers still have the Junk Yards around Mansfield? Are you a member of the Mid-Ohio Sports Car Club? Is the "Friendly House" still there for boys?

Ah... memories of my youth....

Josh,

I hate to say it because you have a bit of poor starving college student aura about you but a broken bolt on the exhaust manifold is often a warped exhaust manifold. Usually the rear most bolt...:dead:

yes you are correct on the rear most bolt being broken off. and this is me and my dads car so money isnt really much of a issue but we just dont want to start a restoration yet on it because we building another garage with an apartment and that is top priority right now. we just want to get the car running right. time is really the only issue because yes i am a college student for another year. but i live at home and have access to pretty much any tool i will need to do the job. this is my excuse to put a header on now

i dont think any of those are there now. the junk yard have all pretty much closed down all we really have is a few small wreaking yards and miliron. no i am not a member of the mid ohio sports car club i have been to a few events with them but i dont think they ever get to race on the track (insurance issues) they mostly do auto-x events out at the mansfield airport and at ohio state mansfield campus. wish they could race on the track i really want to take the zed around it. and yes friendly house they are still around as far as i know i used to play basketball there back in 3rd grade. mansfield has really gone to crap alot of it is run down i dont really live in mansfield i only put that because hardly anyone knows of bellville.

i also cannot wait to get out of here...

Josh.......I like your first idea.....a leak in the front cover behind the water pump (caused by electrolysis). It's easier to check than pulling the head, and a good place to start. Head gasket leaks are many times accompanied by white smoke from the exhaust! Pull the water pump and check her out. If that ain't it.......pull the head....It's usually the #6 cylinder that leaks.

i have already pulled the water pump and i didnt see a hole anywhere in the front cover but i will check it out a little closer. i have a feeling it is the head gasket though.
