Re: How long to change lifters ?

that totally depends on your experience with working on engines

i would say 5-6 hours?

Do my own work on my s10 and silverado , just never inside the 3.8 .

Are there any bolts that are hard to reach in the rear ?

The first thing that comes to mind is the bracket on the back of the passenger side valve cover. One of the bolts on the water neck threads into the lower intake manifold, and there is 2 hidden bolts on the inside corners of the lower intake manifold you will see when you get the UIM off. You will also need new rocker arm bolts; they are TTY. The LIM bolts require blue loctite, and break easily. Thats all I can think of for now.

Are you certain it is a lifter issue? Lifters don't usually die on an unmodded L36.

Re: How long to change lifters ?

Sounds like the famous Lifter tick , sounds like its coming from under the intake manifold , Thats what I plan on changing when I tear into it , and go from there .

Anything can go wrong modded or not .

first of all, did you change the oil?

does the tick go away after the engine has warmed up?

i had a nasty lifter tick before (my lifter was completely collapsed) but something got jammed in there, and it went away

is the idle affected from this tick? how loud is it?

edit* the reason i ask is because you might not have to change the lifters at all.. i was getting ready to, then my ticking all of a sudden stopped and hasnt returned since last september and ~5000 miles

Re: How long to change lifters ?

Yea , it been making niose for a while tried everything short of changing them .
Seafoam , oil changes ......

It's time to change them and hopefully that will do the trick .

Idle is fine , but I had a misfire code on the Autotap last weekend when I checked it .

Re: How long to change lifters ?

i went all the way to the block the other day, and i had it tore completely apart less pulling the heads in about 3 1/2 hours. the hardest thing to do, and someone mentioned it, is to get the bracket on the back of the motor off to get the valve covers off.

Here is how i did it: you can remove the uim and lim without taking the valve covers off, that gives you a little more clearance to get to that cramped bolt. I also have a set of gear wrenches, totally made it easy. anyways got the uim and lim off and put the wrench on the bolt, and beat it with a hammer. came right off.

Re: How long to change lifters ?

Gear wrenches are a must! I'm just saying, that a lifter tick can sound an awful lot like an exhaust leak. Worth shining a flashlight around the manifolds to look for any carbon buildup before tearing the engine apart.

Re: How long to change lifters ?

Oh, and watch out for that plastic coolant elbow coming out of the LIM in the front. If the LIM has never been off the car, then it will probably tear.

Re: How long to change lifters ?

when i did mine, the car had 140k miles, both elbows broke, so i replaced em. even if they dont break, its totally worth going to the help isle and buying new ones.

Re: How long to change lifters ?

What size is the bolts that I'll need gear wrenches for ?

Thanks for the elbo tip , I'll replace them .

Not an exhaust leak , I'v checked with a stethescope to see where sound is coming from.

Re: How long to change lifters ?

the bolt on the back of the head is like 13mm, thats the main gearwrench bolt. but you can maybe just do it with a standard, gearwrenches are kinda price-ee.... the ones on top of the UIM are 8mm, and the ones in the LIM are in it so you will need a 10mm 6 point socket., Oh thats a good tip, use 6 point sockets on everything.
