rmsnoel Posted January 5, 2013 Share Posted January 5, 2013 Either lad would be grand but a 10 worked better on a cold engine. change oil every year. . At 115k hold.open your tb and using 1finger and a old rag give it a wee clean. Dont use engine flush. Clean throttlebody and check pcv valve by pulling it from the rocker cover with engine running and revs should jump. Next check.the idle.valve. It sticks easily and causes judder. with your airbox pipe off and engine running pull.the plug off tje sensor.on.bottom of tb. yoir revs should rise.Finally, with engine running and everything normal, unscrew oil cap. your revs shouldnt change. cover oil cap hole and uncover a few times. This.tests your piston rings and breater pipes.Apart frim cleaning your distributor cap pins and replacing or.testing.your air temp sensor you engine should be grand for another 20k Quote Link to post Share on other sites
