Tap Tap Tap

[PhilGTR]

My engine seems rather noisy once its warm. When i first start it in the mornin when its cold its nice and quiet but once its warm it a bit louder with tapping sounds. Will changing the oil to something thicker get rid of that?

that oil should be alright,

do a flush when u change your oil, let it run through for a wile be4 u dump it!

does it sound like its coming from your rockers?

Not another RB26 with a bearing about to spin... It doesn't sound good if it comes from the bottom end.

Was it always like that? If yes it could be lifter noise if it started recently not good news.

Hmm im not sure where the sound is coming from really but I will check that later. I just had the engine rebuilt so I dont think that would be the problem of spinning bearings (well i hope not). I can only hear it when im outside but not in the car and I can hear it more when listening from the side.

you could try going to a thicker oil and seeing what it does. but in this cold weather you are probably better off with the thinner oil.

If thats the case and they did the job correct its probably lifters, the clearances are to big.

Who ever put the engine together did they check them? If they are not familliar with Rb26's they may have them backwards. In RB26's the inlet clearance is bigger that the exhaust and thats unsual.

Well im pretty sure they checked it cuz i remember they had to send the head back to the guy who was doing it to get the clearences right. The guy who rebuilt mine has rebuilt many rb26's including his own... the tapping isnt really loud but i just dont like the sound of it. my engines done about 5000kms now and hope it will be ok, Im going to talk to him about this when i get it serviced with him soon.

Thanks for the input guyz.
