I think my vehilce may be one that does not like GC. I have about 1600 miles on GC in my '04 Land Rover Discovery and the Valve Train Clatter worries, me. The last time it sounded this bad the dealer said it was a quart low and to change the oil ever 3k miles. Well I keep checking the oil and according to the dipstick it is full, and then some.
When I start the engine in the morning there isn't much if any clatter at idle. On previous oils it would tap, tap, tap, on start up and settle down within a mile or two of driving. With GC every time I get the gas I hear tap, tap, tap matching the engine speed until its drowned out by the exhaust, above 2k RPM's, not sure if it's gone at that point or if its just coverd up by the exhaust.
No matter how long I've been driving when I come to a stoplight and then accelerate it tap, tap, taps again until I reach 2k RPM's and then it's pretty quiet. I could turn the radio up then I don't hear it but that doesn't sit well with me. I just took a 358mile trip and when ever I would accelerate I could hear the clatter. Cursing I could not detect anything only when accelerating and an occasional tap at idle.
I went and bought some Lucas Synthetic Oil Stabilizer but have not added it yet because I'd have to drain a quart. I know some time today I will probably either drain a quart or dump it all and use the Lucas.
When I added GC. I drained the engine until there was no oil dripping from the plug. Replaced the oil filter with a K&N oil filter and added 6 1/2 qts of GC.
The engine sounded pretty good for the first couple hunderd miles and then while I was listening one day. I heard the clatter start again.
Any thoughts? Should I dump it or is this normal with GC?
