yesterday i blow the gap pf a spark plug in a race and i remplace the spark plug and car ran good .. 3 hours after the car start to smoke white on exhaust .. Today i drive it again and when parked let it on and the amout on white smoke is constant with oil smell .. Like burning oil .. I check my oil lvl and is a lil below the low mark ... Ideas???????

 

Head gasket time.

 

Headgasket??? When is burning oil???

 

pull your head and have a look. maybe a valve isn't sealing up right or the headgasket is done

 

Correct me if I'm wrong but isnt blue smoke normally burning oil, white smoke is burning coolant?? Either way it would still point to a headgasket though I guess

 

Bump this! I've got the same issue, but mine is on a brand new built block with a new head gasket just installed...

Engine has barely seen any boost and I know my head studs are torqued exactly to spec

Also put new cams, valve springs, retainers, and seals in while the block was getting built....

Help!

 

Did you lose any of the spark plug in the engine, like the ground electrode? If so, it could have damaged a valve, valve seal, piston face, or cylinder wall, or all of the above. I hope that wasn't the case. In any case, I'd say the head has to come off, unless you have a borescope, and the issue is readily visible.

 

Start pulling spark plugs out. check to see if theres any oil or coolant on them. I'd do a leak down test.

 

I also have this problem.....

Yesterday I did a compression test and all were a little low, but two were lower than the others,

They were 130/130/150/150

The ones with low compression had oil on the spark plug threads when I removed them...

Pretty sure it was the headgasket, bc embarrassing story.... I actually installed it wrong like 3 weeks ago, but never started the car, so I flipped it, it still looked good.

So I've been spitting white smoke also but my coolant has been full, I've been losing oil though.

Took my head off and this what I found....

Looks like there there was all kinda of oil and coolant mixing and slowly seeping into the cylinder.... Also my new pistons with 600 miles on them have all kinds of carbon build up on them, so I'm sure that has to be some nasty stuff in the combustion chambers.

I'll let you know when my head gasket comes if that solves my problem but I'm very sure it will, good luck

 

I did loose the gap of the spark plug .. I dunno if it melt of break .. car work fine and boost fine is just smoke and burn oil

 

I've got same issue new build new every thing I'm hoping its just in need of a good tune

 

If you see smokes from abuse, then perform compression and leakdown tests. If the smokes just come from nowhere, clean out the PCV valve first.

 

The head gasket helped mine a lot, but still spits a little smoke, I replaced the pcv valve and had no luck, in the process of installing a catch can to try and help
