Justin Posted January 20, 2004 Share Posted January 20, 2004 Erm, I have to say......... yes Chris I have Not often. In fact I have once hit 22 psi (1.5bar) on a track day. Other than that I let off the throttle when my boost light comes on at 17.5 psi (1.21bar) I was dreading the piston ring and cylinder chamber symptoms as well as the Turbos please say it isn't so This could be a defining educational moment in this forums history: Remember - Don't go over 18 psi(1.2bar) boost. Look at the internal pictures of Justin's block! It cost him £7,000 to sort out. Are there any obvious checks for me to do before I book it in with you to do a re-build:( Cheers J. Edit: I had one of your restrictor plates in place on the track day so could have hit 2 bar if I didn't have it in! Link to comment Share on other sites More sharing options...

Dude :flame Dev Toyota recommend a 10w oil not because a lighter oil will cause excess oil consumption, but for protection in hot climates and anti drain back reasons. If the engine is sound using even a zero weight oil shouldn't cause excess oil consumption. I am not recommending using 0w oil, just saying it shouldn't cause excess consumption. But hell, what do i know, I have only been using Neo 0w oil for 10 or so years in all sorts of engines whose makers recommend a heavier weight oil, and none have burnt oil or leaked it past the oil seals, for reasons of reduced oil drag.

Guest Terry S Posted January 21, 2004 Share Posted January 21, 2004 Justin, give it a try, they sell it in Halfrauds now. Chris, I have to say that I know a lot of people with MKIV's who have had high consumption on Mobil 1. Maybe it is excessive boost, but a heavier oil seemed to cure it. On my first engine, which experienced high consumption, when it was pulled apart the rings, pistons & bores, infact the whole bottom end were all fine.

What was causing your high oil consumption then? the oil must have escaped somewhere Link to comment Share on other sites More sharing options...
Guest Terry S Posted January 21, 2004 Share Posted January 21, 2004 It's difficult to say. The consumption was fine if I used synpower or Castrol RS 10/40. This wasn't the reason for changing the engine FYI. I had a fully built one so when the stocker came out we took it apart to see how it had faired after many 1000's mile abuse.
