dragonsfyr Posted March 22, 2008 Share Posted March 22, 2008 OK so I've now had Ghostie for 2 months and last Sunday I put oil in her ( she seems to consume about a quart a week and we hadn't figured out yet where it was going). Monday she starts PUKING grey blue smoke out her exhaust in 1st and 2nd gear. Only when cold and only when under HEAVY acceleration (she is also making upper end "rattling" noises during this). Today she starts doing the PUKING all the way thru 3rd gear. She is an '88 Comanche, 4.0L (for the last 7 years she was "babied" by the guy I bought her from)........I don't baby my rigs I drive them how they should be driven. My question is has anybody run into this issue and if so where do I start for the fix........My mate thinks Timing Chain because the problem is inconsistent. Sunday she will be parked when I get home and I will get the XJ out for DD until we can fix Ghostie. Link to comment Share on other sites More sharing options...

JeepcoMJ Posted March 22, 2008 Share Posted March 22, 2008 if it were timing chain, it would CONSISTANTLY not run :roll: rings, valve train. you've got a top end issue...i say rings. check your airbox. you probably need a rebuild or just a new motor.

HOrnbrod Posted March 22, 2008 Share Posted March 22, 2008 Ghostie?? The truck's probably pissed off.......... :roll: Link to comment Share on other sites More sharing options...
jtdesigns Posted March 22, 2008 Share Posted March 22, 2008 Ghostie?? The truck's probably pissed off.......... :roll: Or possessed!!! :D sorry, not much help with your problem, but I'll try to keep ya :D Link to comment Share on other sites More sharing options...
dragonsfyr Posted March 22, 2008 Author Share Posted March 22, 2008 She named herself...........She's grey and has skeletons hanging in the windows........a skull hitch receiver and shift knob......Her name is Ghostie......much better than what the other guy called her ("The Unit"). I will be driving my wheelin' rig (Purple Haze) until I can resolve Ghostie's problem........If I have to rebuild the engine then so be it. I just need more input on what folks might think is going on. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted March 22, 2008 Share Posted March 22, 2008 I'd take "the Unit" over ghostie.... how bout "the Member" hahaha Link to comment Share on other sites More sharing options...
Mitch Posted March 22, 2008 Share Posted March 22, 2008 Could it be "blow by"? Is that where oil makes it past the piston rings and gets burned up and out the exhaust? Would that be consistant through all the gears? Link to comment Share on other sites More sharing options...

Would that be consistant through all the gears? That'd have to be alot of oil.. I think its a headgasket,, when it gets hot the metal expands and seals the leak... Hey dragonsfyr have you pulled your pulgs to see what they look like?? Link to comment Share on other sites More sharing options...
dragonsfyr Posted March 22, 2008 Author Share Posted March 22, 2008 We have not pulled the plugs yet. As all the tools are at my house in the back of the XJ. I am not home on the weekends. What am I looking for on the plugs? OIl buildup? Soot? Carbon? or all of the above? Link to comment Share on other sites More sharing options...
Mitch Posted March 22, 2008 Share Posted March 22, 2008 I have a feeling if you pull them, you are going to be able to find the odd ball, or know if something is wrong. Link to comment Share on other sites More sharing options...

What am I looking for on the plugs? OIl buildup? Soot? Carbon? or all of the above? yeah,, if its rings the plugs will look like there covered in oil,soot, or carbon. You can check the oil and see if its milky, the oil fil cap for the same, if coolant is leaking into the cyl the coolants fluid level will be down.. you can hold a piece of cardboard up to the exhaust tip while running and see if you get any condensation.. They make a test kit for the coolant that tells if the fluid has exhaust fumes present , but the Jeeps system is closed, so I don't know if it would tell you anything.. EDIT: I just read where your losing coolant so do a wet compression test and you'll find what cyl is to blame.. remove power from fuel pump and run compression test.. Hopefully its just a head gasket and not a cracked or warped head... Your plugs will help you determine what is going on too.. The bad cyl will be cleaner then the normal ones..

dragonsfyr Posted March 23, 2008 Author Share Posted March 23, 2008 Um....NOT losing coolant at all......losing OIL about a quart a week (I only drive a couple miles round trip to work and then about 100 miles round trip on the weekends)....NO water in oil checked that first. The oil is being consumed internally. SO pull plugs and check for sooty deposits, etc. Link to comment Share on other sites More sharing options...

I bet one or more are wet with oil.. Link to comment Share on other sites More sharing options...
FxRacing282 Posted March 23, 2008 Share Posted March 23, 2008 I'm going to say head gasket or blow-by. do a compression test and then do a leakdown test when the motor is cold and when it is warm. this way you will know if it is the head gasket or valves Link to comment Share on other sites More sharing options...
dragonsfyr Posted March 23, 2008 Author Share Posted March 23, 2008 Thanks for the info folks. I will do the checking next weekend as I won't have time during the week withthe new job and all. We will 1) pull plugs and look for deposits. 2) compression test when cold then when warm. Is that about right? It's been too long since auto shop in HS.........What is a Leakdown test? and how do I perform it? Thanks again. Link to comment Share on other sites More sharing options...

Its what you could call a reverse compression test.. instead of turning the engine over to get compression you introduce compression into the cyl.. (air pressure) then hold that pressure over time and see if any pressure is lost.. Good way to test valve seals, seats, and rings.. You can get the tester online or you could barrow it from a shop.. I think harbor freight has them ,,I know northern tool has them, for a decent price.. Link to comment Share on other sites More sharing options...
dragonsfyr Posted March 31, 2008 Author Share Posted March 31, 2008 SAD NEWS: Ghostie is parked indefinately. compression test .....inconclusive (this according to my little brother who is an ASE certified mechanic). However they found evidence of water in cylinder #5 and lots of oil in the rest. There is still no oil in the water and vice/versa. HE "played" with it for several hours today and before he can say the rings are ok or bad we need to replace the following. Definately needs: Head Gasket & timing chain When that is done we do the compression test again and the leakdown test. Link to comment Share on other sites More sharing options...
