My GZE's Tappet noise

[IBMFD3S]

heshan Wrote:Guys, my GZE after a even a non-eventful drive, starts giving this "tock, tock, tock, tock.." noise for about another 10 or 20 mins..

My mechanic says this is my tappets making a noise due to not having sufficient lubrication..

My engine has enough and more engine oil and he feels that the engine heats up too much and the engine oil becomes watery and that the tappets run almost on a watery lube..

Can this be? I haven't experienced this before with my engine for an year as its been an year since i put the engine..so I'm not convinced that this is lubrication problem and he suggests I put a oil cooler. I know this will help with the general health of the engine but how can I confirm this problem will be solved before I spend a bit more cash?

Please help.

thanks,

yes I think it's possible. very hot oil will lose it's lubrication and turns to coke overtime. another cause for losing lubrication is compression loss (piston rings) -> fuel reaches the oil and attacks the oil and lowering lubrication. other way around too, oil lowers the octane of gas when mixed. so yes, when oil gets like water it lubricates less and especially possible when a cheap oil from the groceries store is used.

guessing this of course because I didn't hear it:
first thing too do is to be 100% sure what the problem is, could be some bearing too (like the bearing of an alternator) so try to locate the exact problem. after that it's finding the cause which could be a search or found easily. with an adapter under the oil filter you can fit an oil temp meter for example.

but when the car is designed not to have an oil cooler I guess that is not the problem unless you are raping the car (drifting) and have a lack of wind so it lacks cooling which drives the temps skyhigh.

there are old farts on the world with loads of experience who say 'ohh it's your <fill in part>' or they get a long metal part and put it on the engine to hear where the knocking is coming from. find such a guy if not sure about your mechanic.
