Default If my F13 was one of the faulty ones...

My lifters have very light wear and from what I can see, it looks like maybe 1 or 2 of the cam lobes look to have wear. I really don't want to pull the cam because a) I don't have time and b) I'd have to put the car up on jacks and break the crank pulley bolt loose which I really don't feel comfortable doing. So if my cam was in fact one of the faulty ones, what would happen if I just replaced the lifters and left the cam alone? I'm sure these lifters would eventually wear too, but I'm looking for any option right now that doesn't involve pulling the cam.

You dont want to pull the cam, but you want to replace the lifters? You do know that you have to take the heads off to change the lifters..... john

If you dont change the cam now, you are going to end up pulling the heads AND the cam again later......guaranteed.

I assume that you are not wanting to pull the crank pulley off?

I did whats youre thinking of and replaced my stock lifters with mellings, but left my f-13 in the car. 6K miles later I had to pull the heads again. Show us a good high res picture of your lifters and possibly the cam through the lifter bores or bulkhear windows. Might be able to tell from the pics wether or not youre at particularly high risk. Can you feel ridges on your lobes with your fingernail?

Pretty much.

If you have the mechanical ability to pull the heads yourself. The pulley shouldn't phase you at all.

Plus, pulling the cam will be simple, seeing that you dont have to worry about dropping the lifters.

Yeah, but can the radiator, fans, and crank pulley be done from the top? The car isn't movable at the moment and I won't be able to get a jack under it. That's my problem.

Yup, all that's done from the top actually. The only reason you'd need to jack the car is easier access to drain the radiator, and to lower the pan for the oil pump.

You can get to the radiator drain without jacking the car up, and you're not messing with the pump at all, so you're fine.

Like he says, you can do everything easily from the top. I just did my latest heads / cam without it on ramps like i usually do. The petcock (read: drain) for the radiator is actually far forward enough that you can reach under the car at ground level. The only thing you really cant get to is the oil.

I could do everything from the top. The only thing you really need to do from the bottom is to install the oil pump.

I would definitely pull that cam out! If you change just the lifters you are not really fixing the problem.

Also, you should not have to pull the oil pump to swap cams.

true, but many people replace the oil pump when swapping cams. I'm sure he has already done that, I'm just saying that's the only thing I *had* to do from the bottom, oh and to lower the oil pan. You might have a hard time getting the front cover off depending on how high your car is. The two bolts on the bottom would be almost impossible to get from the top I'd think.

How do I lock the flexplate without jacking the car up?

If it's a maual, throw it in 4th gear and grab the e-brake. If auto, I don't see any way around getting the car up in the air to get the starter out...
