Unhappy ISL Head Gasket Replacement

Hey,

We are looking at a coach that appears to need the head gasket replaced. It is wet by the head gasket, and the valve cover interface looks dry.

So has anyone had one replaced lately? Roughly how much? I am looking for a ballpark figure for negotiations.

thanks

Have him pay to fix it, then buy the rv...

This isnít a repair you can defer for a later date. Youíre going to pay $$$$ for a head gasket replacement. May involve pulling the entire motor...

And... they may find more to fix...

As a seller, I would totally want to sell as is...

The coach has very good access from above. The bed is north/south and the access panel is basically almost the size of the queen bed. Also side radiator.

I guess I should have added that upfront in the original post.

I would rather I the price drop and I pay. That way I can be more assured of the quality of the repair. But I understand some would agree with your comment.

I would call Cummins and get a quote. This could be a simple head gasket replacement or it could get expensive. Things might break taking off the head. Iíd magnaflux the head after removal to make sure itís not cracked. Figure for the worst and hope for the best.

If the head needs replacing figure on $5,000 at least. On my ISX just a reman head is almost $5,000 and labor was $105/hr a couple years ago.

Just something to keep in mind. Head gaskets usually don't fail for no reason. Has the engine been overheated? Is the head warped? Those are just a couple of things that could have caused a head leak. I hope you are getting a substantial discount on the rig (like $20,000-30,000) because this could get very expensive depending on what happened. Good luck.

Or a cracked block. I would have him fix it and pay someone to inspect the repair.

OK. Maybe this is not as bad as I thought. Feel free to snicker. Here is another view of the oil. Well in this picture it is rather easy to see it is above the exhaust manifold.....so this is not a head gasket problem.

That is good news.

It still needs to be addressed, but it should not be as bad of a problem as first thought.

Ideas an comments certainly still appreciated.

thanks

OK, I thought we were talking coolant, my mistake. This looks exactly like the oil leak I had on my my ISL. It was coming from a badly sealed engine brake spacer. This spacer sits between the head and valve cover. It’s needed for clearance for engines with engine brakes. Mine was sealed with RTV. I believe some of the newer ones use a gasket. It involves removing the valve cover, two engine brakes and spacer. I’d figure about two days if you’re doing yourself. I adjusted my valves while I was in there.

Agree^^.

Looks the wettest just under the #6 injector. Very little moisture by the engine brake connector. #6 would be my prime suspect.

Wet with what:


Engine oil
Coolant
Diesel fuel

No snickering at all. Good to see someone admit to a mistake. Lord knows I make more than my share. Glad to see it is a minor repair.
