GTi.Si 0 Posted May 17, 2009 I need to know what pressure my VR should be producing at set revs. I've heard so many different pressures I don't have a clue whats right! The reason I ask is because my brand new Mocal did this: http://i30.photobucket.com/albums/c307/ ... C00941.jpg Sent it back and mocal said my engine is over pressure, but they also claim the cooler is tested to 110psi and rated to 150psi and it will require considerably more that this to deform the aluminium. I dont have any oil leaks (which I would expect if my oil pressure is over 150psi!) I have replaced the oil pump but my cheap gauge is still reading over 100psi (which is all the scale goes upto). I have access to a sykes picivant (sp?) garage gauge, but need to know what I should expect. Quote Share this post Link to post Share on other sites
Toad 0 Posted May 17, 2009 Wow. Your relief valve may be jammed shut, causing massive oil pressure. Which is not what you want. If your guage is going over 100psi, and you bummed the mocal, then I think you have a pressure issue.... Quote Share this post Link to post Share on other sites
GTi.Si 0 Posted May 17, 2009 Thats what i'm thinking, but what the chances or having a stuck relief vavle on a new oil pump aswell?!! Also I took the old pump apart and the valve moves with relative ease, doesn't let much air through though if I blow through it. Quote Share this post Link to post Share on other sites
Toad 0 Posted May 17, 2009 hmmmmmmm. Could be somethign more serious if you've had that issue before. Head gasket failed to oil gallery? Dunno really... Quote Share this post Link to post Share on other sites
GTi.Si 0 Posted May 17, 2009 Yea, sorry. The cooler burst before I changed the pump, hense the new pump. Don't think its head gaskit as there no oil/water mix and it doesnt use water. Surely that would make it low oil pressure aswell? Thinking mabey a blockage in an oilway? Quote Share this post Link to post Share on other sites
Toad 0 Posted May 17, 2009 I really don't know. It could be a lot of things. Sorry! Quote Share this post Link to post Share on other sites
GTi.Si 0 Posted May 17, 2009 I'm open to any suggestions! Don't realy know how to cure it short of changing the engine, which seams a little extreme! Quote Share this post Link to post Share on other sites
GTi.Si 0 Posted May 18, 2009 Anyone got any ideas? I'm rapidly loosing interest in this car! Don't wan't to break it, but its looking more likely every day! Quote Share this post Link to post Share on other sites

GTi.Si 0 Posted May 18, 2009 To be honest I have been thinking of going turbo or rotrex for more power, but I have this problem to fix before I do. I'll let you know if I do get rid. Quote Share this post Link to post Share on other sites
