Has anybody asked what year the OP's S2000 is, I'm assuming it's an S2000.

Also worth looking at this thread: https://www.s2ki.com/s2000/topic/974...g/page__st__50

 

It is a 2004.

 

well they have stripped from the top and its not the top of the engine so waiting to see what they say tomorrow i would think! going to pay them a visit tomorrow to see for myself!
they did ask how long i had drove it since i had the engine cover re-powder coated and if the gargae that did it could of dropped anything in it! obviously i said no but i could see he was wanting to try and blame them and wash there hands with the problem but will see what they say when they strip the engine down more! i think all of you are going to be correct with the problem which is the bit that scares me the most!!!!!!! will keep you all up to date!

pleaase offer your advice and comments please

cheers

Well if they'd dropped anything in it when they did the rocker cover, it'd be the top end they buggered so that must indicate it wasn't that, surely?

 

Have they drained the oil yet and sent it for analysis?

 

The first port of call is to systematically check things.

Firstly check the compression, then check the oil pressure that will then pretty quickly give you a good indication without spending massive amounts on diagnosis and something which you can do yourself or a garage which wont cost the earth.

A un-cleaned/unfinished rocker cover refurb may have caused your issues.

I haven't read all your content, as to be honest i can't be bothered deciphering your poor English, grammar and formatting of your posts.

 

well just to update you! i dont know if they have done any oil compression ratings yet! with regards to it being the re-powder coated rocker depends if the rocker cover had some of the shot blast particles let on it but i asked a mate of mine and he woudl think that it would have to be quite abit to block the filter or oil pump.

but it was beautifully clean from the outside!!!! im sure it will be this knowing my luck but what could i do as the garage was doing it all!!!!!
i suppose i can go back to them and tell them to sort it but i would expect they would kick up a fuss about it!!! i feel like the bad person where i am the victim if it is this!!!

will update u more when i call at the gararage tomorrow!

 

There is enough room by the cam chain tunnel to drop a nut/washer or even a small spanner down. I don't know if the is anything that would stop it going right into the sump. It could lay in the sump untill an uneven road surface could dis lodge it and then be picked up by the spinning crank.i cannot imagine anybody ignoring that and just going ahead and running the engine
If the OPs description is right it could be something lodged and the crank hitting it every revolution.

Generally if its a heavy thudding its the bottom end if its a lighter rattle its the top.but not always.If it had been me looking I would have taken the sump off first and had a good root around. It sounds like something you are going to be able to see.

It is a terrible shame and the guy did nothing wrong, so hopefully they will find something that points the finger at somebody. You would need a small shovel full of blasting beads to block the oil pump pick up.In my experience cranks do a lot of rumbling and groaning before they go, but if a cap has broken or something is lodged then that would explain why it all happened so quick.

I wish you the very best of luck and hope its nothing that can't be put right either at their expense or cheaply by you.

 

hi all thought i would update:

well we actually have a diagnosis.... which is just what you have all been saying, the powder coated engine cover is the culprit! the extra uncleaned particles they use to sandblast the engine to get the old red paint off has not been cleaned from a particualr part on the underside of the rocker cover! this has then gone around in the engine in the oil and has filled the whole oil filter up (they cut it in half)and also has destoyed the turbines or vanes in the oil pump causing the shiny finish on them to be destroyed and also the bit that causes the pump to keep pressure in the system has failed ( sorry for terrible description) this has then caused loss of pressure and oil starvation which in turn has then caused the egine to develop faults.

they now have to strip the whole engine down to see whats damaged but more than likely what you guys have said!!!! and as these particles have been round the engine so many times it maybe a new engine!!!! one good bit is that as it was a garage that did all the fitting and powder coating service this should be down to them to pay for it all!!!! spoke with them today and they will call me tomorrow!!with whats going to happen now!!!!!

will keep you up to date thanks again for all your helpful messages

 

Can I confirm firstly:
1. When you topped the oil it took 800ml to get to top of the dipstick?
2. You had the car for only a few weeks 4 or 5 I think you said?
3. It's not your main driver (you've a company car you say)?
4. Can you confirm how many miles you've owned the car for?

I have a couple of other scenarios beyond you've Donald ducked your engine (although the news isn't much better)

One is that the oil level has been on the low side and you've driven it so hard through the corners that the oils sloshed out of the sump meaning it draws air and mullers the bearings.

Two is my favourite though if my above comments are correct. Previous owner mullered the bearings by running it low on oil or a king it. Realises what they've done and sell on quick. You buy the car. Oil light starts to flicker causing you to look at it and add 800ml of oil to fill it up. Damage starts to manifest and you're in a world of trouble. May well be a issue proving that though.

The logic behind thinking this scenario is that even for brisk road driving only 800ml down from top should still have you above minimum. Slap on the wrist for not paying attention and letting it get that low but not something where you should be considering hari-kiri. You get oil pressure by pumping oil into a confined space. If there's no confining of the space (such as bearings breaking down so the oil ways just piss it back out into the sump) then oil pressure drops and you get the warning light flickering. If you've only had it a month or so and only done weekend driving I suspect you've only done 300-400 miles. That's the sort of distance I'd be expecting shot bearings to chew on themselves happily for before spitting themselves into the sump.

Again this isn't something I can prove but may fit the circumstances if I've understood your circumstances correctly. May not help you with getting the engine sorted either since a private sale would have no real comeback and garage sale would be difficult to prove that scenario.

Ok my timing sucks, ignore the above
