Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello John and Welcome - My name is XXXXX XXXXX Im happy to help / advise you on this issue.
Im sorry to see you have had a wait on your question - I have been asked to help you -You dont mention the mileage but this issue is usually caused by a general lack of servicing over the years - at least, that accentuates the issue - its not the only cause - it can come on anyway ..I note you have changed the oil - but the engine should have been flushed using a good quality flushing agent - and then replace the oil - and a new oil filter.. and then see if that cures it.Generally the cause of this is gumming up with carbon over the years inside the engine - it creates a sticky goo like surface on the working components - so you need the flush to get rid of it - and then ensure a good quality - and correct grade oil is used - all of which works to eradicate this issue.The oil to be used by the way is a 5/30.. you can use a 10/40 - but the former will help rid this issue for you.. Too - this engine has manual adjust type tappets / rockers - not hydraulic - so have the gap settings checked as well... often these don't get done even on garage servicing over the years.Working through as above should see thus cured for you John -Let me know if you need anything else - I will be back on shift later should you need.
