Engine noise, tapping?

[stozza]

Have had a noise for a while now but has only recently got noisey!

Sounds like a diesel! :S

Do the tappets ever need adjusting on the 172 engines?

And is it a easy job to get done?

 

[stozza]

Oh and it disapears the higher the revs go?

i think the tappets are hydraulic ones mate, they work with the oil, have a search on here someone did have a tappet problem but you have to remove the cams etc to change them so its a pretty big job !! also some people may say diffuser pulley as well, so whilst you have the belt and cams off it would be easier to change as well...

The dephaser pulley you mean! If your lucky it might just be a noisey hydraulic lifter.. big-ish job to change but wont cost to much. I had a similar noise but it turned out the cam journals were scored and it scraped the head.

 

[stozza]

Was that expensive?

I'm going to change my oil tonight and see if it helps!

 

[SkidMarx]

Yea it was expensive.. i just stuck a new engine in!

Followers are a doddle of a job - common fault. Ive got loads in stock £10 each. Try a better grade of oil - thats usually the cause of the problem

Done a oil change, using Mobil 1, 0w40 and its still there?

If I need the followers changing will I need a new cambelt fitting because of the belt coming off and being re-tensioned?

mate i get exactly tjhe same thing on mine, especially when its cold, when it idles it sounds like a diesel and makes a horrible like rattle tapping noise as i pull of between 2-3 k revs, but as u say higher revs it fine! Just wondering if you have worked out what the problem is on yours yet?

 

[stozza]

I'm having it looked at tomo at Rentech, aparently it could be a few things?

Will let you know!

 

[stozza]

Been to Rentech and told its the phaser pulley, booked to get done next saturday!

Fingers crossed!

how much will that cost need mine done got the same noise engine rocking but goes after 2k then drives tidy very lumpy on tick over

 

[stozza]

Give Mike a call at Rentech! ;-)

I think its a about £300? Depends if you get a new or used phaser pulley?
