Tapping

[SpeedBird]

Can anyone tell me why the engine is tapping like a good one.

when cruising at 50 blah blah can't really hear it but when your going slow or standing still even pulling away its there. The tapping does get slower when slowing down.

Have got Oil


??????

Thanks

as above stuck tappet or something such like...

 

[turbojay]

worn/ stuck tappets(lifters)

either give it a good service and that may quieten them down but if you really want to . . . replace them but only use genuine ones.

people drive with them tapping for thousands of miles but is worth getting them replaced for a quiet engine

they get worn due to poor oil and/or lack of servicing

yeh sounds like your tappets souldnt tap for to long tho

 

[jezzasin]

ive noticed this with my car, when i start it in the morning it sounds a bit like a diesel, would these hydraulic lifters be what i need?

 

[turbojay]

depends what you mean by diesel, if its tapping then as i said a good service may sort it out or its been left too long you could try cleaning them out or replacing

They also pack up due to nothing more than wear, sometimes the spring inside that holds the steel ball against the seat snaps.
Pattern ones are fine, some genuine are crap, in 27 years I've had a few problems with tappets, nearly all were genuine.
It is worth changing the oil if needed then adding some wynns hydraulic valve lifter lube, silenced many with this over the years, will work almost instantly if it's going to.

i take it that wynns stuff just goes in with the oil?, might get some see it if helps

 

[jampot]

Ive flushed an old engine with cheap thin oil and engine flush wynns or stp (not changing the filter run up and get hot leaving to run then taken a very steady drive re drained new filter good quality oil, This made them very good although not perfect but the rattle went from 4-5 mins to 30 seconds. 2 cause as above the ball retention spring fails or carbon build up makes them blocked.

amen to wynns bloody good stuff

 

[tabetha]

Yes wynns just goes in the oil, awsome stuff, they can be damamged beleive it or not by scratching of the seat the ball bears on, carbon in the oil is VERY hard, but doesn't build up on flushed engines!!

IMO pattern ones are a waste of time, been there done it, ive seen many threads saying pattern ones sound worse than the genuine worn INA lifters.

If your going to go through the trouble of replacing them then for god sake get genuine INA lifters

 

[tabetha]

I've got GENUINE INA in my cossie, as you'd expect, oil supply is perfect pressure is perfect oil gallery was cleaned out as I did it, every one of the 16 oil channels was checked, and f*****g noisy INA tappets 3000 miles later, 2nd set different noisy ones in a different place on head.
Interestingly the last 2 sets of BGA tappets I fitted are silent, I firmly beleived in INA, being a german firm, but quality has taken a severe nosedive based on what I've seen the past 2 years.
Just about to rebuld my bottom end on cossie after around 185,000 miles, but BGA tappets will be going in, not found a faulty one yet, shame I can't say that about INA, I even use WAHLER thermostats, german quality as best I've found, so not anti german, as I was born there, will use what I fond best.
