Now I have never had problems with holding the car at high revs(over 7k) before but on the rollers on Thursday and on the road tonight I can actually hear what sounds like noisy tappets for a minute or so after a some spirited driving (160+).

I know this is prob just the need to move to solid lifters but why is it doing now after all these years?

Oil temps are never above 90 even though it is very warm tonight.

Thoughts and ideas?

they have a short life at the rpm you like to give the car stick a new set in or go solid

rapidcossie

Cheers Tony.

They have lasted well.

Not doing any damage am I? they do seem to recover quite quickly.

they also get noisey if the oil level is low i take it you have checked that already

rapidcossie

yeah good oil press(60psi+) and its slighty above max when cold.

i had nearly new lifters put in mine recently and it still sounds like a diesel, is that anything to worry about?

So i take it take it of your going to be reving to over 7500 often it realy is better to be on solids.

you'd better stick some 1.8 diesel lifters in there

the lifters can sometimes take sometime to settle down,take it u got good oil pressure,oil in her etc?

lozi

i dont have an oil pressure gauge, there is oil in it yes lol

how many miles u done on these tappets ?

lozi

over 1k but im unsure

you can hear them at the start of this vid

a bit rattly is it better or worse then before u fitted them?

lozi

about the same tbh

what grade of oil u put in?

Could be little ends starting to wear. My last one sounded very similar to that.

Can also hear a slight noise from maybe a tensioner or something too for a second.

BigErn

Euan how long you been running with these lifters in mate?

Solids would be the way to go in your car I guess, anything that revs high and spends a lot of time up there will kill hydraulics fairly quickly.

thats sounds horrible and not how an engine should sound imo. Regardless of it being a cossie engine

foreigneRS

how old is the oil?

RickyLee53

Do you notice a drop in power/missfire as well?

Solid is the only way to go IMO. We've had to do it on all the engines that are rev'in high. (non cossy)

rapidcossie

car did "only" make 465 ATW onthe rollers but so might be a slight drop in power.

no misfires at all.

lozi

i use silkolene pro s 10w-50



the car had a brand new cambelt and tensioner recently




sorry again for hijacking

rapidcossie

done about 20k miles probably.

CossieRich

20k at your power levels and revs. time for a change i reckon Euan

stage 3 muppet

i found my 2wd did this and i traced the cause back to the oil pump gasket was flawed and sucking in air ....
which in turn causes air in said tappets instead of oil lol...
i now always use some gasket goo along with gasket just to aid the sealing

when the guy fitted the new lifters to ma old cossie thy rattled there brains out then re checked the timing an it was,nt bang on when he had built it back up , when lined it up perfect they were silent , maybe check the timing ?

yep 20k miles on the rolling road

rapidcossie

LOL its done that on the orad over the last few years.

I was out in the car tonight and limited the revs to 7200 and the tappets were quiet.

i used to get this on the rally car after a long stage, the things i found out through trial and error - do not use synthetic oils, only use good quality mineral oil and i changed it after every event - about 60 flat out stage miles and maybe 100 or so road miles, and change the filter with every change, this seamed to stop it, though i did go to solid lifter eventually, as will the new engine be on solids.

not really pratical to change it that often on a road car tho IMO

markk

iTrader: (2)

perhaps not, but put it into perspective about how many hard road miles you do and adjust accordingly, you probably do no more than a mile at a time with your foot flat in every gear, in our cas across a 60 mile stage 100% throttle at max revs happens very often mate
