Question about Mini Cooper S

1 Answer

Head gasket replaced skimmed and valves reseated. After running for 3 to 4 days,sometimes from cold and also after a journey,if stopped and left for a short period and then started it sounds like a Diesel. Hydraulic timing chain tensioner has been renewed but it has reacurred.Could it be the hydraulic tappets or oil and oil filter? and what is the solution please.

Hi i presume you changed the oil and filter when you did the head if so it may be the wrong rating as if i got it corect it sounds like a diesel when you start it after its been left the last thing to get oil is going to the camshaft and rockers so if the noise goes once it has been run for a minute or so and sounds ok then using a oil that is recomended by the manafacturer unless its done a high mileage then use a higher mileage oil with an oil additive STP something like it as what is proberly happening the oil running back into the sump and having to be pumped back all the way to the head . yates210456

What causes slow acceleration wit very loud exhaust noise


I would check for a large exhaust leak, somewhere between where the exhaust manifolds attach to the engine heads to the muffler. Since you had the heads done, I would inspect the connections between the exhaust manifold & heads, the manifolds and the down/flex pipe, and the oxygen sensor housings.

Hi. I can give you a simple, but time consuming test to do to check your intermittent compression problem. New hydraulic lifters cause a lot of problems until its settled. Remove the camshafts and the hydraulic lifters. Take each hydraulic lifter and put it in a vice(becarefull not to damage them) and squeeze out all the oil in the lifters. Then put them back and replace camshaft and allign timing marks. Check compression ratio. What happens sometimes is that the oil pressure is too high(stuck oil pressure release valve or cold thick oil) and this causes the oil pressure to put so much pressure on the hydraulic lifters, that it slightly forces the valve open. That will cause your low compression as well as backfire through the intake.

Did you replace the thermostat? Does it overheat? You could have just over filled it. Just run it a couple of days and watch the heat gauge. If it keeps bubbling out of the expansion tank I would recheck the torque on the head bolts. You will have to loosen them up and retorque them in sequence, from the center back and forth out to the sides.

My Toyota Hiace high roof with 3L Diesel Engine heats up. This was after the cylinder head was skimmed and had new valves replaced. Please help me. How can I stop this heating up? Cannon


Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..

2003 saab 9-5 replaced head gasket because of overheat


disconnect computer and drive it ,if it drives ok then nothing wrong with it,after test drive put your hand held plug in gizmo under wheels and drive over it for what use it is.Skimmed head and new head bolts ?you must have more money than sense didnt you check it with a straight edge first??then clean it with a flat bed sander.head bolts ?? more expense .only expense should have been head gasket and antifreeze with a tube of instant gasket.Have you put all the little vac pipes back on that open the flaps on the air con and left the one off on the valve between the inlet and exhaust manifolds.Also did you remove and grind in the valves ??
