  1. Dude can I just ask did you have piston at tdc when you did the leakdown test? Did you also make sure the engine is at operating temperature. You do realise if the valves in the head are open it will give you a false reading...

    If you did do the test correctly, you gotta understand no engine will have 0% leak because an engine needs to allow crank case pressure to escape. Crankcase pressure travels to your dipstick, oil filler cap, pvc and any other head drains which may be present. On average most engines leak between 5-10% of the air which is compressed into the cylinder. You really need to have a gauge that tells you how much air is leaking out. If you find you are leaking more than 10% but below 20% it just means engine has some wear on it however once you start passing mid 20's it means you got a major problem.

    You need to redo the test and get the actual percentage of loss which is occurring... unfortunately if you did the test correctly and you have a 30% leak going through the cap and dipstick it means you got piston landing or ring issues...

  2. I started playing it again after 3 years... can't get past rank gold nova1. I've noticed it's really random, I have games where I ace and then 10 minutes later I find myself anchoring.

  3. Welcome dude - there's a wealth of knowledge on these forums.. make sure you use the search function regularly and if you still find yourself caught up do not hesitate to ask for advice!

  4. I'd put my dollars on valve stem seals then cause your compression numbers aren't bad enough to be blowing oil out your exhaust... also note that if results are unchanged between wet/dry compression test it generally means rings are not your problem... sometimes valve seating can cause a drop in compression. That's another whole issue to worry about but should not result in burnt oil!

     

    Plus you just changed turbo and a little bit of shaft play shouldn't be causing any issues like what you're explaining...

     

    Dude one other thing, make sure your pcv isn't seized up... it really assists in lowering crank case pressure when the manifold is in vacuum. It's an easy thing to look at while you wait to do a leak down test!

     

  5. If you blowing oil on deceleration, especially down them big ass hills it generally tends to lean towards blown turbo or valve stem seals...

     

    If blowing oil on cold start it could be cracked ringlanding or bad valve stem seals...

     

    If you blowing oil on hard acceleration it could be rings, ringlanding or turbo seals...

     

    It's honestly such a flamin mongrel to find the issue...

     

     

    Steps to resolve this:

    1. Both dry and wet compression test.

    2. Leakdown test.

    3. Check turbo for shaft play.

     

     

    From my personal experiences, I had blue smoke on cold start and under high boost/rpm application. Lasted 12 months and my engine crapped itself- turned out I had a small hairline crack in the ringlanding which developed to a catastrophic crack.

     

    If you are from West Sydbey, I can refer you to the guy I used to work for - he has a fetish for jap cars!

  6. Were they second hand? Did they get cleaned/tested? Never seen trouble like that with jecs 550s, saying that if you're buying now go with top feeds for sure



    I bought them of a club member, they were practically brand new. He had the original receipts and paperwork. He had bought them from a supplier in Perth who claimed they were flow matched within 2%.

    I got them cleaned and tested before I installed them. The spray pattern was awful and the injectors were not flow matched within 2% error like they promise. I seriously replaced them with a top feed setup a month after I had them installed!
  7. Could be rubbing on the timing belt cover. Mine did the same.

    Front top cover isn't on... Can I ask did the residue it was creating feel tacky sticky. Like I couldn't get the black shit of my hands without giving them a decent scrub in mechanics soap.

    It could possibly be rubbing on the bottom cover or on one of the bearings...

    Thanks for the opinions! Really trying to get as much info as I can before I replace the timing kit.

  8. Do a warm dry and wet compression test. Also do a leak down test.

    If you're saying it's coming straight from the exhaust ports then I would definitely say it's got nothing to do with your turbo unless it's leaking through the seal into the compressor side!

    Also check your breather setup - make sure your pcv isn't blocked or any parts of your crankcase ventilation setup!

  9. Wasn't sprayed with TAC2 or something was it?

    Honestly feels like it was! Lol

    I definitely didn't spray anything on it when I installed it. There is abit of oil build up around the bung that I've put in place of the VCT solenoid but the black crap that's building up on the belt is just way too tacky to pass as oil build up.

    It seriously feels like that black gasket maker paste...

    I'm gunna have to replace the whole timing kit - timing belt is way too serious to be overlooked.
