Guest kenny stag Posted August 25, 2013 Share Posted August 25, 2013 Hi all you nice people,I have a 1989 mk4 with MFI engine, the tappets are getting a bit on the noisey side, what do you recommend the work to sort them out. Cheers Stag Quote Link to comment Share on other sites More sharing options...
StuDaBear Posted August 25, 2013 Share Posted August 25, 2013 You could try a oil and filter change, failing that a new cam and lifters should cure it. Quote Link to comment Share on other sites More sharing options...
Guest kenny stag Posted August 26, 2013 Share Posted August 26, 2013 Thanks stuDaBear, Are the tappets on the CVH engines adjustable. Cheers Stag Quote Link to comment Share on other sites More sharing options...
Guest Mk4 Kenilworth Posted August 26, 2013 Share Posted August 26, 2013 Techncally they're not tappets but cam followers and because they,re hydraulic they self adjust. Quote Link to comment Share on other sites More sharing options...
Vincygav Posted October 31, 2013 Share Posted October 31, 2013 You could try Wynns hydraulic valve & lifter treatment lubricant. It comes in a 300ml bottle. Just add it to your oil. Quote Link to comment Share on other sites More sharing options...
Guest Rob90spec Posted November 1, 2013 Share Posted November 1, 2013 if you've not changed the oil recently do that 1st,after that........whip the rocker cover off,take off all 8 rockers/followers,change the tappets,refit everything,job done..........60mins max Quote Link to comment Share on other sites More sharing options...
welshlad Posted November 1, 2013 Share Posted November 1, 2013 I agree with escort si 130 - try Wynns hydraulic valve & lifter treatment lubricant and a engine flush and fresh oil would do them good too Myself in the past ive took them all out and popped the springs and bearings out and give them a clean in gunk and thats made them quieter etc (you have to prime them tho before they go back in) Quote Link to comment Share on other sites More sharing options...
Guest ROJ Posted October 11, 2015 Share Posted October 11, 2015 resurrecting an old topic - Our P reg 1800 ghia has just developed tappet noise. Question is, can we wait until the service in January to sort it, or will it cause damage if we do? My wife uses the car daily, but only on very short runs.

jinks Posted October 11, 2015 Share Posted October 11, 2015 hi stag I just replaced mine just check cam and rockers for where . if worn replace them it would be pointless if you just changed the lifters. And torque nuts on rockers to the wright settings . mine sounds good and runs good now Quote Link to comment Share on other sites More sharing options...
