Head Gasket Leak

[M82A1710M]

Oil is ozing out the front of the engine between the head and the block and I realize I need to change out the head gasket, however, it isn't a torrent of fluid. My question - would it be safe to drive about 300 highway miles before changing it out? I have a trip coming up this weekend and want to bring the truck.

As long as you anr't loosing compression, or mixing oil into the water or water into the oil you should be ok.
Mine leaks between the head and block also. But it doesen't loose enough oil between changes to worry about.

I agree with Ken, although I can't guarantee anything. Mine seeps a little right at the front. Some say it is from running high rpm's, but it is pretty rare form mine to see more than 23/2400. It bubbles a little even at an idle. I've got a headbolt wrench on the way and will try a re-torque. If that does not stop it, I'm not going to worry too much. It has run that way a long time.

2400 is only a couple of hundred from red line.

I drove mine with "seaping" head gaskets over 700 miles to the floor all wound out with out a hick up. If its not running rough, smoking, knocking, go for it. p.s. after I rebuilt the top half of my ltd-465 ( new gaskets, heads shaved, reground valves, ect..) it leaked soon after. It runs 100% great, starts like a gas motor, just is super and it leaks. From what I saw at Fort Mccoy last month almost every deuce leaks something some where and thats how it is.

mine has been leaking for 10.000 miles
it stared when i drove it to fort Mccoy
its not bad 2 gal in 10.000

buddy of mine has been running his puking for the past five years with no issues yet. But then he's pretty easy on it.

Thanks for the vote of confidence guys. I'll treat it well there and back.

Here is what PS Magazine has to say about it. It's normal, I guess. My engine doesn't seem to be hurt by it, close to 6,000 miles since December and most on the highway with 2,400-2,500 rpm for hours on end.

 

[Desert Rat]

Yep, me too. 2450 rpms and slobber slobber. Oh well, I got places to go and things to do!

What are the odds of it going from seeping to squirting? Thanks.

Hey...it is 30 plus years old. Anything can happen.

I am wondering re head bolt torque, too. Is it ok to set the wrench to the prescribed torque value and re-torque (tighten down) the head bolts?

Mine is seeping from the front as well; darn fan blows it backwards and upwards, oiling up the inside of the hood.

It only seeps at high rpm, under load. Practically nothing at higher rpm when testing with the hood open.

I know it is a defect, but I am somewhat reluctant to go through the whole head teardown process, just for that bit of oil.

normal?? only in the sense that they all do it. certainly not right, and i doubt a retorque will do anything at all. the issue is the very old technology head gaskets. when replaced and done correctly, with the new gaskets, you will just be amazed at how dry it stays.

I must agree with this. This is what I've noticed as well.

i would like to know what kind of gaskets you used, and how they were installed. the old style gaskets had to be coated in certain areas with permatex or they would leak, i have never seen the mil say how to coat them. the civ engines were done this way. all things considered, new style gaskets are the only way to go.
