Hoping to find some good karma after a day of feeling like being on the end of some really bad karma so here goes...

Truck: 1995 FZJ-80. Currently 198XXX miles. Engine top end gone through (head, valves, new headgasket, etc) at 175XXX miles and at that time a new Safari turbo system was installed.

Background: Bought the truck in Oct of last year in CA and it has sat there since with only intermittent starts, etc. but probably hadn't been started in a month or two before this morning. Got to it this AM and battery was dead but nothing else seemed wrong. Put new battery in it and it ran perfectly. Ran around Los Angeles and worked my way over to San Bernardino (probably ~150 miles) of lots of highway, city, stop and go, starts, etc and no issues at all.

Got to the Colorado River just before Needles and the CEL came on. Engine did not run differently but still pulled into next gas station to check it out. Seemed a lot like the P401 EGR flow CEL but did not verify. Coolant level good but oil level was about a quart low. Outside temp was 105-deg F. Got a gallon of water and a quart of oil, topped oil off and pulled ECU fuse to reset CEL. Got back on I-40 heading east, trying to get to Flagstaff and eventually ABQ. Climbing the highway grade just west of Kingman the CEL popped back on and within seconds the coolant temp went from normal right past the red highest mark. Pulled over ASAP, turned engine off and turned all the heat on high.

Coolant overflow tank was extremely pressurized and spewing coolant out. I guess I lost somewhere over a gallon. Engine oil was definitely leaking but couldn't tell where. It took at least 30 mins for the under hood temps to get reasonable. I put the gallon of water in the overflow tank and it sucked it all in. Checked over everything and found the following:
little hose from metal neck of EGR to brown EGR valve missing
inspection cover at flywheel/rear main seal missing
and the big one...
engine oil dripping down onto the exhaust manifold studs at #6 and the EGR port. This is visible from below but not really from above. It is definitly coming from above the exhaust manifold. Engine oil on the dipstick was all the way down to the lowest mark so it lost at least 2 qts quickly.

No signs of coolant in the oil or leaking at seam between head and block. No signs of oil in coolant but coolant looked like crap.

The truck starts but runs rough. It seems like the turbo is very loud now with a whine, not the whistle it had before.

I had it towed AAA to my friends house in Flagstaff which is off Exit 333 off of I-17 South where it is parked now. I don't have any tools of any sort.

So can anyone help, have ideas, diagnostic input from what I've described? I'll take some pics and post once it is light but it's been a rough and disappointing day.

Feel free to ask me questions that may help and/or call me on my cell: 607-592-8280.

Thanks in advance, it is appreciated, and right now really need some help.

Mike Robson

edit: sorry this is so long but trying to be thorough
 
Mike, there are some CSC people up north (Mogas, Gotmud, etc) that may be able to give some advise?

After cooling down overnight, will it start and run without overheating right away? If it does, most likely HG let go. Of not, it could be the AZ curse: If you were flogging the engine, combine the turbo, and the AZ heat, you may have just overworked the engine and overheated. Even the Supercharged guys here in AZ have to make several mods to avoid this same scenario. If it runs ok this morning, Id make sure the rad fins are cleaned up, maybe upgrade the fan clutch, change your tstat (after this big overheat) to give yourself a chance to get out of the Southwest with that Turbo.

How bad is that oil leak? Something else to tackle before leaving if bad enough, or youll be smelling burning oil all the way home :frown:

I agree with you that most likely the missing EGR hose is your CEL. Dont know if this was much help. Best of luck Mike!

Sounds like we gotta find a way to get the 80 to my house. Even if we do a HG project in your friend's house, the block may need some attention and the vehicle will be down for some time. Now I wish I had one of those Turbo Diesel domestic trucks with a car trailer....

Some bad luck bro...

Get back to working on my cruiser. :flipoff2::hillbilly:

Seriously, taking a stranded mudder would take precedence.
 
Subscribed.

Sounds like a HG to me too.


Get that truck over to Ali's.
 
Damn Mike. :frown:
Theres a few guys in the Flag area, hopefully they will check in. I don't have their contact info.

Thanks for understanding. He is a long way from home in NY!!
 
Yeah, I say we get Mike's truck to Ali's and go from there.

Could we just tow it behind another 80? I'm free today and up for a good recovery operation!

Yeah, we can tow it to my house using a Uhaul dolly with a rear DS removed.
 
started it briefly to try and put it in a better position to check things out. ran really rough, no power, pretty sure some white smoke from tailpipe but couldn't see it clearly when giving it some throttle. oil level and color looks ok, no signs of coolant in it. pulled radiator cap and added nearly a gallon of coolant to top it off and fill resevoir to full mark. digital camera battery charging so pics in a bit. going to pull spark plugs and inspect and post back up.

THANK YOU folks for the help.
 
ok, so I can't even budge the 10-mm screws on the spark plug cover plates, most likely from the super overheating. Of course I have only a leatherman....
 
pics

well the engine is screwed and vehicle is not going anywhere under its own power. pulled the plugs and first one was covered in oil and electrode burned off. The remaining ones don't look bad though, especially #6. other pic is where oil is coming from. The air intake tube was completely coated in oil with it puddled up going into the throttle body. all in all pretty devastating. I still have no idea what and if anything happeded to the turbo in all of this.

Uhaul truck with tow dolly is $450 plus gas so don't think I can swing that right now either. Checking AAA to see if they can help.

Stand by.....Calling.
 
Just got off the phone with Mike. Looks like Mogas is heading over with some good dx equipment, including a Boroscope to ascertain what's happening.

The oil puddling up in the intake could be an indication of the PCV and Turbo thing; admittedly my knowledge in this arena is limited. I think we have non interference engines so the piston didn't make contact with the #1 spark plug is my guess in case the timing chain slipped or something like that.
 
That looks like my dirt bike spark plugs after the piston blows in a hundred pieces. I don't know much specifically about cruiser engines but I would defiantly be looking for chunks of metal by the drain plug if my spark plug looked like that.
 
update 16:29

#1 spark plug electrode is melted, possibly due to pre-ignition. The plugs were for NA engine, not FA engine. New plugs were bought.

Compression test results:
#1 - 30 psi (not good)
#2 - #6 - around 125 psi +/- 5psi (normal)
 
Update:
16:52

Boroscope revealed a hole on top of Piston #1. Looks like classic detonation scenario due to *perhaps* too lean condition. Maybe the Unichip and the ECU didn't compensate properly for the quick elevation gain?

I'll head up to Flag tomorrow and bring it down to ABQ using a dolly.

That's great, but that does not explain the coolant thing. It still has to have a bad HG, or some high pressure path from the combustion chamber to the cooling system.
