Question about Suzuki Grand Vitara

Open Question

I have a 2000 Suzuki Grand Vitara 2.5L V-6. After having someone replace the head gaskets and changing the oil a few times the oil light is starting to come on. It starts out with no light but within 5min its blinking a bit. When driving it only blinks at normal driving 2000 RPM range but I also notice if I put it in neutral while driving and rev the engine to 3000-4000rpm the light goes out. (I guess due to more oil flow/pressure) But after driving a little more the light starts to come on more and more often so I brought it home not wanting to risk any more damage. So I'm guessing the oil pan pickup tube is maybe clogged as I know it did not get its oil changed anywhere near on time its whole life and know they can build up a lot of sludge because of this. Sure enough I was able to lower the lower oil pan some (I cant believe you have to take out the front differential and a lot of other major stuff off to get the upper and lower oil pan completely out!!!) and can reach in a few and remove most of the sludge by hand Although I can not see it) and there was a lot! I can feel the end of the oil pickup tube (But cant see it either) and it had a lot of crud on what seems to be the screen on the end too and I have been able to clean it up somewhat by hand and can try to soak, spray or otherwise clean it better. I really don't have the tools and am a little leery of removing all the stuff I need to to get to upper oil pan out and replace the oil pickup tube, seals etc. So I'd really like to try to to just remove the sludge by hand and clean it and the pickup tube end as best possible, scrape the sealer on both lower oil plan surfaces, reapply sealer, bolt up, replace oil filter, fill oil, and see if its any better before trying to do the ton of other work needed to get to everything the right way. One of my problems is I do not know the construction of the oil tube pickup and flow from there and if there are other filters that are very likely clogged up above. But with all the sludge that was in there I believe it was just slowly sucking up and clogging the end of the pickup tube after startup and a little driving. Therefore I'm thinking it could only be better after quickly trying this! What do you think?

SOURCE: I recently replaced head gaskets

Bill,
Generally when this condition occurs, there is a leak in the oiling system. The most likely cause is a bearing the has excessive clearence. Look up into the block with the pan off and see if one of the cam bearings are spun. This will cause a loss of oil pressure with no knock. This can occur if the engine overheats which I will assume is why you replaced the head gaskets.

SOURCE: suzuki grand vitara 2000 model the engine light blinks

Take your rig.. drive it to a gas station.. fill the tank up with gas.. also fill 2 jugs of gasoline at the same time... put the jugs in the back of it.. now drive as far as you can until the rig runs out of gas.. then, take the two jugs of gas.. pour it all over the rig, inside and out.. now light it a-blaze, then walk to your nearest car dealer and buy a new car..

Sounds like an ignition component failure check for proper resistance through primary and secondary ignition coil windings, refer to service repair manual for exact specs, also the ignitor magnetic pick up may be not up to snuff, the only other ignition component to replace or check is the ignition module and/or plug wires themselves, sometimes when extreme demand is put on the ignition system the plug wires must be high quality and completely isolated from one another. Spark plug wires when routing cannot come in contact with one another in the slightest proximity.

make sure when you're cleaning the mating surface on the head not to let anything drop in the the head itself otherwise you will have more probs than an oil leak

I THINK I HAVE A BLOWN HEAD GASKET IN MY 00 GRAND VITARA SUV, IT OVERHEAT AND SHUTS OFF ALSO HAVE TWO OIL LEAKS. IS IT REPAIRABLE OR SHOULD I BUY A USED MOTOR


Hi,

Yes this is reparable both the head-gasket and the oil leaks.

Just price up the cost of a second hand motor and the repairs of the head-gasket and oil leaks.

Go with the cheapest.

Thanks

Leaking from valve cover. other than changing the the gasket what can be done now that the top is removed in order to prevent from having this charge to me a second time around for something else. My 2003...


Other than replace it with the correct gasket. Not much.... You can get a neuopran gasket as oppose to a cork gasket. There is a few dollar difference but not gonna solve the problem completely you'll get a few extra miles before it leaks again.. This is a common maintence problem. Gonna happen again in another 65k miles The valve cover gaskets take a lot of vibration from the head as well as heat.

03 Suzuki Grand Vitara dsl overheating!


Its probably not boiling what you are getting is preasure from the engine which can be caused by a faulty head gasket but as you have that changed then it must be a crack or warp in the cylinder head. Get the head preasure checked for cracks and warp. If ita warped get it skimmen if cracked you will need to replace.
