Rings??

How do you test for rings??

Compression is even on all cylinders albeit it low at 8.5bar, but that was with a cold test. the car smokes its ass off on boost. If i give it some welly i see the smoke in the rear view mirror and when i change gear theres one huge gigantic smoke cloud 😳

Turbo has just been rebuilt and i can smell the oil. Plus the smoke is a little darker than when the oil seals are gone. 😢

I think my actuator on the turbo is faulty or something. On teh way to work it boosted to 1.4 bar 😮 fcuks off like that but eish thats not good. will check it wen i get home.

But how would i test for rings? im not in the mood to pull the engine again. And the bank manager doesnt want to pay for a new gasket set + rings and whatever 😢

Still drives a feck load better than last year 😀

fixed the crazy boost thing now

Valve stem seals and or guides... ? 😢

Thanks 🙂 could you explain a little more? where can i get one and how does it work.

and have you removed that little breather washer thingie?
also thought my motor was shot - removed that restrictor and no more smoke - magic

1st thing i looked for. Couldnt find it 😕

It is in that short pipe going to the PCV valve right?

No it is the restrictor washer in the turbo side of the tappetcover breather pipe going into your air intake from the air filter.

Glad I could help you out widowman....with the washer thing, I thaught I was the only 1 with this washer thing....I am not alone anymore!!!!

OH! well that sux coz i dont have that pipe anymore anyway 🙄 sh1t

If that PVC valve is blocked it can also cause to motor to smoke... but mostly on idle

Checked that 2.
I cant believe the rings are gone, that engine looked so spotless. All breather pipes where clean, head was clean clean clean. pulled off sump everything was clean even the oil in there was pretty damn clean. the spark plugs even looked good. Only the waterlines looked rusty. Reckon i need a couple water flushes

a little trick i heard of is to drip about a little bit of oil (clean) into your combustion chambers. it would be say 5ml's i think. then redo the compression test. if it goes up drastically then your rings may be stuffed.

but the leakdown test is the real way to do it.

didn't have oil left to drop in, so i used sugar
should work and it smells nice too

What does the spark plus look like after a short run? Soot, lots of carbon or clean? 🙄

sticky, but it smells like candy floss
burnt my tongue quite bad though

they where clean the first time i pulled them. Going to check again in the week now that i have more km on them

Daniel, you know of course that I follow these threads very carefully? Why, because my sx is doing the same since a week ago. Great balls of white smoke during decompression, sort of smoke during acceleration and also smokinf badly during idling. And if I touch the feul pedal slightly during idling, it also smokes like hell. I can smell the oil burning. One other thing though - I dont get the boost up to 1 Bar. 0.5 the most!!!!!

Some members tell me it is turbo seals, and then we get the answers on valvestemseals etc. I need to do compression test, remove turbo geuso meter with other to check boost. To check sparkplugs.

So you slightly in front with the problem solving.

Cylinder leakage test=
pump compressed air into cyl while at tdc. Air runs through a gauge which shows you a percentage pressure loss.
Anything over 20% leak is poked you can also listen at the intake and exhaust for air leaks past the valves.

If there is plenty air coming out of the breather with no intake or exh leaks then the rings are shot.

Thanks Calibrator 😀

Freddie i dont get smoke on idle at all, or perhaps not yet anyway 😕

Anybody know where i can buy or borrow a Cylinder leakage tester

its not cheap hey... expect to fork out above R500... Last one I saw was over a R2000 but it was as Snap-On item. And you'll need a compressor.
