Must be the extra k's accrued on the cruise yesterday

[Beer Baron]

did you change the tensioner when you did the timing belt?

[Trust33]

Doodz it might be a belt tensioner.Have you recently installed a heavy duty clutch?

Its not to do with that

definetly not the clutch either.

I would put money on it being a sticky lifter, especially since he changed the oil last week and with a different type

My car is doing the same thing and was told it might be the lifters but someone else said its the injectors because its an RB26, dunno which is right but i want that sound not so loud, and its on idle aswell

The injectors are always noisy on every skyline i have heard, but on GTRs (especially older ones) the head does get a bit noisy, they dont have hydraulic lifters which when working properly are quiet, the head in a gtr will just be a bit noisy all the time with age

My car isnt THAT old.. its a '94 model (the last year they were made ) .. it was coming from the front of the engine/fuel rail ..

if i was to upgrade injectors would it be not so noisy? Because it sort of worries me.

if it does make them quieter, good excuse to upgrade them

ok update...

mechanic found two problems that might be causing the noise..

water pump was loose, banging against itself.

and the ac tension bearing pulley was sqeeking

got both parts at justjap $183, but i bargins and got it to 180$ LOL. I think this was SAU price too..

well by old i mean say more than 5 years old <_<

New injectors are quieter, but wont be forever! I wouldnt worry about it, just make sure they are clean and they should be fine, they are all a bit noisy!

[Mintie]

dood go and get a long screw driver and listen to ur engine, this happen to all skyline...........so dont worry.......try using motul 8100excess.......and it would go away.....the lifter is tapping the top so it ok...

if u rev ur engine up and it tick,tapping...then it could be ur cam bearing.........

[GRKGTR]

I hope its just something small like that or nothing at all for my car otherwise i wont be happy!

[T04GTR]

its all about the oil.

what viscosity is the motul oil your using?

25lifters can be very sensitive to changes in iol thickness. the oil feed to the head can also block up

undo the oil cap and see how much oil is getting up there.:

i spose the easiest way is to chech it with a friend with the same engine

ps. there should be enough oil to splash evry ware with the oil cap off.(just the odd splash out of the oil cap with a continuase swirl of oil around the cam lobes,if thats any help

cheeres

[T04GTR]

ahh yes the old loose waterpump pully trick
