First you should have check your engine block to see what wear it had before you buy new piston. that will determin what oversize piston and rings to used , will if it come to that , it areally waste of work done

Why is my newly rebuilt 5.7 350 chev. Engine burning so much oil. It's not leaking, and not smokeing out tail pipe?


what was entailed in the rebuild?
cylinders bored and hone , new pistons , rings
crank grind and new bearings
or was it just a ring refresh and sand paper on the cylinders
I'm thinking the latter ( cheap and nasty)
The oil will be coming past the rings and being burnt in the exhaust ( cat converter if you still have one )
That oil passing the rings comes from , glazed bores , rings being installed upside down, ring gaps not being set 120 degrees apart but almost lining up
worn ring lands in the pistons
Sump oil either leaks out -- Gaskets , seals filters or is passed by the rings and burnt in the combustion process

I have overall h100 2.6 engine and put the new piston and and oil pump , when the engine idle it release white smoke all the time, i have tried to run the engine but still no luck.


It certainly sounds as though you've got an oil leak.

Did you replace the piston rings as well? If so, did you use the right size?

Installed new piston rings and gas is getting inside oil


valve not closing is from a bent valve. Black soot is from over fuelling and incomplete combustion. Oily chamber is oil from the rings. It si possible that more than one valve is bent as it occurs from turning the engine over without letting of the rockers when adjusting the valve timing.

1998 astra car is smoking on accelaration


It's time for an engine rebuild. Or you could get a reconditioned engine installed. All depends, if the car is in good condition and worth fixing. But it is a 15 year old car. Might be time to upgrade.

Engine cranks but only way to keep it running is by giving it gas. also smokes


You should run a compression test on your cylinders first and go from there.

unless you have an accurate manual your going to run into a few problems ,if you think it's a good project one way to learn how to rebuild a motor, if you want great results concider one from junk yard ,or parts store rebuilt,no matter what you do it's a big project best of luck . oh ya if smoke is little you more than likely run it longer if you think it's good enough.

My mitsubishi canter 4d32 engine had all its 4 top compression rings broken ie one from each bore what can possibly cause that and what amount of smoke or mist should i expect from the breather after...


As an engine wears the ring lands on the pistons wear also. In addition to ring land wearing on the piston, the bore in the cylinder develops a wear pattern. Has the engine been rebuilt?
If the pistons have worn ring lands and were re-used it may allow the rings (new or old) to twist in the grooves and catch on any ridge in the cylinder, thus breaking them.

When the engine is apart you must check for proper ring land wear. You need to consult the piston manufacturer for proper wear specs, typically around 0.006in.

If you're getting a visible amount of smoke/oil from the breather after the rebuild something is not right. The rings are not seating. I would definitely recommend boring/honing the cylinders and going with a new set of pistons/rings so you don't have to pull it apart again. A little more now can save a lot in the long-run.

General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.
