Cam Change - laugh test

[Canyonero]

Can I change the cam and lifters on my 3.4L without pulling the engine? I know I'll have to strip the intake off to get at the lifters and at least pull my radiator. Do I need to get at the cam cover on the backside? I could possibly do the cam at the same time I do my clutch if that were the case (need a bigger/better/stronger clutch).

I bought a crane H260 cam for my next engine build (described in my sig), but I'm thinking of just installing it now and seeing how it goes. I've been too busy and cheap to invest in the next engine since this one works fine and I don't want to take my Trooper offline while I'm experimenting. Maybe next year, I don't want to screw around with the Trooper until after winter.

I pulled cams out of many cars with the motor in. Take it out the timing cover. On the 3rd and 4th gen f bods, the cam can come out without even removing the radiator

thats because theres like 3 feet between the engine and radiator..lol

Remember if you use this cam and the lifters it comes with you need to note the location of each lifter. Each lifter mush go back on its matching lobe when you move the cam to a different motor or re and re it in the same motor.

Yes you can do a cam change with the motor in the vehicle I did it in my S-10.

changing the cam bearings would be a bitch.. They dont have to be done, but they should be done.. there already broken into the previous cam, so putting a new one in is just begging for one of them to spin..

[Canyonero]

The engine only has 70k miles on it. But if they spin, they spin...

I doubt you will have a cam bearing problem. When I re did my 3.4L I measured the bearings and the clearance was still in spec and it had 107,000kms on it. I only changed them because I did a full rebuild.

[Ortie666]

most of the time they are always in spec, but even a slightly large one wont be the problem, its dirt, and another breakin that will fuck with them.. Ive seen it done lots.. just dont say we didnt warn you

Swapping cams in a front wheel drive car is quite challenging

I've never owned a FWD car. Even my little I-Mark is RWD. I've never actually owned anything but an Isuzu.
