tapping motor

[ChrisPerna]

i bought m 1995 pathfinder a few weeks ago and when the motor warms up i hear a tapping noice coming from the motor, any ideas?

normal

your exhaust manifold is probably warped or the manifold studs are cracked

get a new exhaust manifold or get some headers

its not a valve tap? cause thats what it sounds like

[Tungsten]

you can hear the valves if your exhaust manifold studs are cracked

 

however if the truck doesn't run good, your timing belt could have slipped a few teeth and the cams are smacking valves

ohh okay, so i am going to order headers tonight, should i get pacesetters or thorney(i think thats what there called)

 

i am going to open up a new thred to see how bad it is th install headers. i had a ranger and every stud was cracked because of the guy didnt heat up the the head

[ChrisPerna]

okay so i know its not the timing belt cause the truck had a timing belt job last month and im afraid of getting headers cause i think if i put them in i will brake all the studs, what should i do?

[Precise1]

Have you verified that it is the manifold/broken studs? That you need headers?

 

I'll tell you how hard it is to install the Throley headers next week.

Watch Precise1's thread on Thorleys, I would recommend getting the Thorleys thru Steeevo as Precise1 did also as it is a excellent price & he is a trustworthy vendor.

Truck will sound NICE!
