Tappet noise on cold startup My T31 with just over 1000ks on the clock and its had its first service is noisy when cold
When its cold there is quite a loud tappet sound until (I assume) oil pressure has built sufficiently (a couple of seconds) ...is this normal, or is there an oil pump problem ?

Re: Tappet noise on cold startup All Xtrails are a little tappy when started cold.
Its just till the oil gets to the top of the engine.
It should stop after 3 -4 seconds.
Re: Tappet noise on cold startup Met a guy at a rest stop he was pulling a van and we talked about exy problems he had a tappet type noise for the first couple of minutes when starting he came from a country town so used local mechanic, he found noise was the clutch on the alternater $120 fixed the problem

Re: Tappet noise on cold startup Very interesting, I did not know any alternators had a clutch. Usually they are on aircon compressors I will have to go look at the service manual now.

Re: Tappet noise on cold startup Its not tappet noise.
All X trails motors run Timing chains as opposed to timing belts.
Its the Timing chain cold rattle.
It isnt an issue.
Just make sure you use an oil filter with an anti drain back valve and one day if it does get worse just replace the timing chain tensioner!.
Seriously Guys. I dont mean to be rude but can people refrain from posting the wrong information if they dont know something. It just confuses the poor original poster.

Re: Tappet noise on cold startup off topic but RE: kev
yeh the alternators have a kinda one way clutch similar to a mountain bike, you pedal real fast and then stop pedaling and the wheels keep spinning after u stop pedaling. if you shut off your engine and its quiet around you, you can still hear the alternator spin and slow down for a few secs

Re: Tappet noise on cold startup Stock nissan oil filters have them. Some aftermarket ones will have it too. The autospares place who sells them should be able to tell you.
