HAMLNJ Posted June 29, 2015 Share Posted June 29, 2015 Hi, since I have had my zed, intermittently the engine would knock slightly for a second or two on start up. I have discussed before and the verdict was my valves are probably slightly out of align and not worth worrying about for the age and mileage (114k, serviced 2k ago) Now it's Every time I start the car and getting me worried. Only a couple of secs and doesn't tick or knock while driving. (Slowly or harsh.) The engine is strong and pulls well. When starting the car I am keeping an eye on the oil pressure. When starting it up it seems the oil pressure takes a moment to fire into action. Taking a look at a friends zed (pimm junior) it fires up smooth and quickly . Mines not... Here's a vid I took. Sorry for the non start at first. Just me not holding the ignition for long enough. It's there an oil pump issue? The pressure is fine while diving. Connection issue? Oil too thick? I use 5/30 fully sync. You can hear the knock if you wear headphones. Thanks for reading. Any help would be great! Cheers Ian Quote Link to comment Share on other sites More sharing options...

chippychip123 Posted June 29, 2015 Share Posted June 29, 2015 Personally I thinks that's coming up ok, but was that from stone cold? As mine go's to 90 from cold Quote Link to comment Share on other sites More sharing options...
HAMLNJ Posted June 29, 2015 Author Share Posted June 29, 2015 Used about 3pm, started up At six. So not that cold. If you listen carefully you can hear the knocking Quote Link to comment Share on other sites More sharing options...
Ebized Posted June 29, 2015 Share Posted June 29, 2015 Just a thought.... With that mileage, as a starter you may find an engine flush (if one not done in recent times) might help to clear some of the inevitable sludge that is likely to have built up and my be the cause of slow re-acting guage and other areas of the engine not getting a fresh soaking of good quality oil. If you use the car mainly for short trips that will have added to the sludge build-up but if you are getting around 60psi at 70mph and around 20psi at tickover when hot then that would suggest the pump is OK. And make sure you use a quality engine oil (Mobil1 as an example) and filter rather than what comes off the shelf at Halfords etc. 1 Quote Link to comment Share on other sites More sharing options...
HAMLNJ Posted June 29, 2015 Author Share Posted June 29, 2015 Good advice! Not done one in a while, my mechanic isn't a fan of them. Sludge might be the issue then. Using Mobil oil so all good there, oil change and a flush might be a good start. Quote Link to comment Share on other sites More sharing options...
HAMLNJ Posted June 30, 2015 Author Share Posted June 30, 2015 Well Addtion to the good advice it hasn't work unfortunately. I'm going down the route of having the valves realigned. If anyone has had this done before. Costs and process would be handy. Quote Link to comment Share on other sites More sharing options...
