winchbietch 0 Posted February 11, 2009 Hey Getting paranoid now... Ive now done about 2500 miles since i completely rebuilt my abv engine, but: I have noticed that i have a slight oil leak from the head to block on the o/s of the engine. looking through the forum i have caught bits about having to re torque the head down after the anitial run up - is this the case? With new stretch bolts there should be no reason to surely?.... Also while im here, although i replaced all the chains, tensioners and guides with new genuine bits - should i change my upper chain tensioner for the "all plastic" one and if i do can i get away with leaving the double style chain? Thanks paul Quote Share this post Link to post Share on other sites
andy 0 Posted February 12, 2009 There's no need to re-torque the head. As long as you follow the correct tightening sequence, ie torque figures and then multiple stage angle tightening it should be fine. Quote Share this post Link to post Share on other sites
Roger Blassberg 0 Posted February 12, 2009 If you renewed the tensioner blade with a new one of the old type, it should last another 100 000 miles. If I were you, I would leave it alone. The all polymer type can be used with the duplex chain - at least I hope it can, I have just put one in !! Are you sure that oil is leaking out of the engine, and not simply a slight spillage from the oil cap when filling the sump? Or maybe a weeping cam cover gasket?
