It sounds like some of that water turned to steam in the engine and the pressure of the steam did some damage. Check out the timing chain and the timing mark alignment. Check out the valve condition...there might be some chipped or cracked valves...yikes!

98 chevy truck 350 engine 93K miles when starting sometimes the engine will backfire..could be cold or hot engine..but after it runs for a couple of minutes will run fine..


A backfire usually indicates a timing issue. I recommend a minor tune up, which will include new plugs and wires, as well as checking/setting the distributor timing. An oil change is also recommended after the issue is corrected, as offset timing can cause fuel to remain in cylinder, which then bleeds past the piston rings and ends up in the crankcase with the engine oil.

Why would i have 60 psi in all 3 cylinders. ran great then all at once it started to run bad


anything below 100psi on 2strokes is usless and needs new rings as long as no damage and in tolerance to pistons ! reed valves and crank seals have nothing to do with piston compression , they work on crankcase pressure !

Polaris snowmobile 500 efi indy


Ok I thinking with the info you posted I have a small thing you can check on the wiring harness by the pull start (recoil) side of the engine there will be a small black box this is a relay (Bosch 30/40) go to any parts store and purchase one cost is from 4.00 to 10.00 and replace it what I think is happening is when you try to rev up the machine it's breaking contact of this relay I hope this helps do not get rid of this machine I'm sure it's a simple fix also check for fouled spark plug this can cause similar issues I hope this help

Not sure what to say other than its fuel starvation, if not already done replace the fuel filter in the tank, if no better i would suspect a massive air leak, so replace the crank seals, if there is no primary compression in the crankcsae fuel will not pull through the engine, good luck.

I have a 1986 yamaha 540 srv snomombile and when i throtle it up it bogs out and pops like a backfire do you have a suggestion on what is causing this and how to correct it?


You should purchase a gasket and seal set, pull your motor out of the sled, disassemble the motor, and replace all the gaskets and seals. You can purchase a piston kit on line that should come with pistons , rings , gaskets , and seals.The main problem you are having is an air leak on one or both of the crank end seals. Usually the clutch side seal leaks first. If you continue to drive you will probably score one or both of the cylinders.When you have the motor apart clean your carburetors and replace your spark plug caps. NGK has new plug caps for about $5 each. If your cylinders look good i would consider doing a light hone job and ring replacement. Again if you just buy new aftermarket seals pistons and gaskets you should be able to do a complete rebuild for about $150. Then your engine will be good for another 25 years. If you are limited on funds Just replace the crank seals , clean the carburetors, and put on new NGK plug caps (about $30).

Cylinder 3 misses and has carbon biuld up on plug also looks to have oil on the plug, smell like oil is burning , smokes alot out of tail pipe,oil consumtion is a qt, per 300 miles and it looks like oil is...


Geez!

U got a bad piston rings! U have to pull down the PiSTON to replace the PiSTON RiNGS, oil is getting in ur combustion!

Or

Check also the valve guide oil seal, hope that is the faulty one! 'Cause replacing PiSTON RiNGS will cost a LOT!


Check on that first, Oil in ur air filter means a BLOW BACK gas from ur combustion is pushing the oil into the air filter!

BLOW BACK is a residual combustion air that should have been burned or gone thru the exhaust, but w/ poor seal of ur piston ring, it goes into ur CRANK CASE and into ur EGR system w/ excess oil!

Hope that explains everything!

I have a 97 polaris indy 500 snowmobile. The spark


Wait, it just wont turn over, like the engine won't rotate?, that is either a broken crank, which not unusual for those 500's or you seized it, (welded the piston to the jugs). if this isn't what you mean, and it will turn over but not on its own power, then either your jets in the carbs are clogged, fuel may get to it, but not through it, or your rings are stuck closed and giving you low compression, check this by pulling it over slowly, you should feel each piston completing the revolution with a prominent glug glug. grab your primary clutch and rotate it back and forth, it should have a bit of play, but if it clanks and has alot of play, your crank is busted
