    Thanks Steve, - so a decrease in gasket thickness (going the 0.051 inch gasket) will increase combustion pressure, and if going the 0.063 inch gasket will keep it around stock (maybe decrease pressure by the slightest). This is probably a stupid question to most, but, which one is better? when...

    Cleaning Head Gasket & Inlet Manifold Gasket Surface on VT

These pics are after 3 applications of it, letting it sit for a few minutes and then wiping off. CRC gasket cleaner was good on the surface. scraped with stanley blade, sprayed some...

The VT has done 180K km's. The razorblade worked well to get the gasket off, but not down to the polished finish you...

    replacing loose pulley, need help...

    Replaced the pulleys and belt and all is good. No more rattling sound. I got my parts from metro holden as they were cheaper than repco and were genuine GM too. Cost about 170 for the two tensioner pulleys, two idler pulleys and the S/C belt. 180sc -> you were right, it was right hand thread...

    replacing loose pulley, need help...

    thanks for your help guys. VSl67 -> it sort of does sound like that, however i'm hoping it doesn't come to this. I'm going to replace the pulleys first and see how I go. I replaced the Coupler inside the supercharger yesterday just because I already bought it from ebay. 2 of the bolts on the...

    replacing loose pulley, need help...

    Hey Guys, When engine is idle (and even on throttle), it makes a rattling sound. I was told it may have been the coupler inside the supercharger but on closer inspection, this pulley in the pic is really loose. I can move it back and fourth. Im not sure what the pulley is for but is...
