Hey guys, just bought a FZJ80 for a hell of a deal, knowing that it had head problems. I could use some advice on two fronts: Diagnosing the cause and Determining the Cost to Fix
The problem I see is when driving it, the engine shutters, real quick vibrations that feels like hesitation. This is most prevelant at a range of 2.2k to 3.5k, but probably is just not noticeable below. It's bad enough that the vehicle vibrates. The engine seems to cool fine, but the exhaust is fire hot and gives a slightly sulfer smell. Also, the check engine light has come one. The previous owner, says it has a burnt valve and the vibration is backpressure. Someone else told me that it's a blown headgasket. I'm interested in your alls opinions on it though.
As far as price, heres the poop. I've acquired an extremely low mileage head that I can swap out, but the mechanic I talked to told me $1200 in labor just to bolt on the new head or swap the gasket if that's all it needed. Beyond that, it's 250 for gasket set and 250 for head bolts, which I'm told cannot be reused, they are "stretch bolts"
I'm pretty new to all of these new fangled engines. I was ready to jerk the head off, replace the gaskets and put the new one on, torque it down and drive. But I'm afraid I'd miss something.
Here's your license, call BS on me and tell me what you think
Thanks
Todd
