Hi,

I need advise. We have converted 86 Mazda Rx-7 to run on LPG with multisequential LPG injection KIT. I think that this is first official converted Mazda RX- 7.

Results are great, car is runing strong and what is fascinating overall consumption of LPG is lower by 15-20% comparing to gas. only thing is that tourqe is maybe little bit lower but more smoth over rev range.

But here is problem:

After cca 1000 kilometers car started to smoke badly and it burns 1 liter of oil per 100 miles. Overall preformance is not afected it runs strong. Smoke is blue color and it start to smoke when car is runing or accelerating or aftar decelaration from redlining the car.

I think o ring are toasted but why since car is only 20.000 after new engine was installed at Mazda service. Is it possible that front oil selal is bad and leaking from oil pump into engine

Please give constuctive dvises

That certainly sounds like a failed oil ring. It may have been pinched or twisted during installation. Pull the spart plugs and check them for signs of oil burning. It will at least tell you which rotor is burning the oil.

 

Thx Aaron,

Do you think that front oil seal is bad or internal rings have gone, do you think that this can be due to runing on LPG. Car is really using to much of oil.

Best regards

 

I would like to hear if you have fixed this problem,or have got another car running on LPG..Post some Pics of this setup!..can you Turbo a LPG car?...(will it go BOOM?).
