0 Dave Posted April 23, 2017 Share Posted April 23, 2017 Depends on lots of things mate, main one being the mileage. Is it high miles? Any smoke from engine? Possibly worn piston rings will be the main cause. Quote Link to comment Share on other sites More sharing options...
0 noodels Posted April 23, 2017 Share Posted April 23, 2017 could be just the gauge, if they are all within 10% is the main thing. could try a better oil. Quote Link to comment Share on other sites More sharing options...
0 Ace lacos Posted April 24, 2017 Author Share Posted April 24, 2017 Car is on 140k all 4 cylinders were 140 psi , car hot and wot , I did post earlier as I think head gasket is on its way out , bubbles in rad , and some times pops the expansion tank, yeah it does smoke a little , thinking about getting a leak test done , when cold it don't feel that eager to rev , think it need a bit of tlc , valve clearance, cam belt and water pump , and oil change and plugs , just don't want to spend loads on it if the engine is past it Quote Link to comment Share on other sites More sharing options...

0 Ace lacos Posted April 25, 2017 Author Share Posted April 25, 2017 Topped up oil and now it's smoking a fair bit , so looks like I'm going to cut my losses and look for something else Quote Link to comment Share on other sites More sharing options...
