have you checked your leads,dizzy cap for mist of oil stopping good spark,spark plug gaps ??? i usally change my spark plugs every 3k miles

kevmc

To be honest with you im kinda new to it only my second rs mate i know a bit about them but im dont know whats happened with it il check plugs and leads. This happened before i just let the car cool down drove it and the chapping went away and it ran fine??

Every 5 years for me at that mileage

Stuck lifter possibly?

I had the same experience, when i went on the dual carriage way and put my foot down one of the lifters kept sticking, turned out it was badly domed so i changed it and it never happend again..Few things you can check for, Hope you find the problem soon though.

I thot about the lifters when i heard the chapping but would that make it misfire quite badly the engine has just been rebuilt and is very quite this only happens when its hot as well??

Was the engine set up after rebuild?

kevmc

Yes was set up i checkedboil it was on min so i just topped it up there still misfiring and tapping at top end its driving me nuts

Do you know what the oil pressure is doing as in got a gauge fitted to check?

When you say top end are you meaning from the top of the engine?
On the rebuild did you have the head rebuilt also? I would whip the rocker cover off and have a look at your lifters/cam

kevmc

No dont have a gauge this has happened before but it cleared dusnt seem to be clearing now tho

kevmc

Yeh it was all done mate i thot about doing that would dodgy cam or lifters cause it 2 misfire tho?

Yes is could

kevmc

Started the car up today still missing and chapping drove it along the road a bit and it went away its fine now lol what can this be??

Jim Galbally

sounds like you could so with getting the car to an RS turb specialist for a checkover at the very least mate. why guess and randomly start swapping parts when they will KNOW what the issue is and just change any parts that need it

First what is chapping lol?
secondly glad it has sorte ditself (for now), as mentioned above a faulty lifter not opening the valve properly. Might be a good time to get a new set of good quality lifters (and maybe a cam while your at it)? Not a hard job, can be done without removing the head. Also give it fresh oil and make sure you run the cam/lifters in properly. Ideas on this vary slightly but the main thing is to avoid idle for the first half hour and use plenty of lube (that's what she said!).

Good luck mate

kevmc

Thats wat i think it is mate dodgy lifter took it to a mate hes had them for years thats what he thinks as well il try new cam and lifters oil change see how i get on.
thanks alot for the feedback

I had a K reg, 1.4 orion cvh with a blocked rear breather that somehow used to stop the lifters functioning correctly. I presume crank case pressure was stopping oil getting to top end???

Now you've described what happens this makes sense, I told a lad I knew what had happened when my car broke down, he said pull the breather pipe off that runs from rocker cover into the block and check the stub on the block is clear, or more so he told me mine would be blocked, he was correct. Worth checking out for the time it takes, I unblocked mine and fitted new lifters and it was alright for a months till I got rid.

I hated the car so when I unblocked it I just pushed all the crap into the sump

If your is blocked I would remove the sump, as you don't want all the crap floating about

i personally think it would do no harm to change the leads plugs rotor arm and cap tbh as he said its only happening when hot and the engine is running quiet so for me that would expel valve or lifter, sounds ignition related to me but thats only my opinion
