    recommend-to-change timing chain mileage?

    I looked at the paperwork for the 91... it got a new/reman engine in 2001 at about 95,000 miles... its got about 170,000 on it now.
    I'm replacing the water pump soon, maybe this weekend. If i don't break any bolts off, I'd rather not do the chain, lol. Mostly because I want to do the intake gaskets in the same day (and not take ALL day), and I wont mind doing the chain 30-50,000 miles later... It's not a mess down there either, the crank seal is pretty dry.

    Anyone got stories about how sloppy their chain was at a specific mileage? Help me be lazy.

    I also have a few other things to do that day too, front shocks, fuel filter, re-set the dizzy (the TFI module is almost touching the t-stat housing...)
    Fixing the steering column issues got me motivated to give her more... she's been trouble free aside from needing a transmission pretty soon after I got her. Time for lovin'... she might even get HO upperstuff and a P71 airbox...

    really hard to say....since the engine is a reman, not factory original, they may have put in a good quality aftermarket chain so it may last quite awhile if not abused, I am from the old school "if its not broke, don't fix it"......

      I doubt it needs a timing set after 75,000 mi if they remanned the motor. Checking it is easy though. Just unsnap the distributor cap and watch the rotor while you turn the crank back and forth with a breaker bar. There should be very little to no slop before the rotor starts to turn.

        ^ what he said, I'd check, hopefully they put a double roller on there and it doesn't have much slop, although after 120K my double roller was pretty loos...but if you don't mind doing it in 30-50K miles, then you should be all right.

          I replaced the double roller set on the Mark VII at 225k, and it wasn't that terrible. It had slop, but not nearly enough to have been cause for concern. There was no danger of it jumping or anything. Single rollers won't hold up nearly as well, so it really kind of depends what they put in there. If some fool found and installed a plastic gear set, those are often hosed by the 100k mark. Second the rotor check to see whats going on with it.

            At 190k I was in the same boat as gadget. Some slop, but not scary. I only did it because I was resealing the cover and I was already in there.

              I did mine because it needed a water pump and the balancer replaced. I was a handful of bolts away at that point and I already had the new part in my hand.

                at the age these cars are at, i usually pull the timing cover too if i'm doing a water pump and the cover gasket has never been done.

                  Did mine at just over 122K because I needed to do the water pump. Gears/chain still looked good but I had a "Forrest Gump moment" - since I already had the pump out I might just as well keep going....

                    How much more is involved to do the timing chain say for expample if your doing the water pump?

                      I could be wrong but I don't believe you need to remove the harmonic balancer for a water pump replacement so you would need to do that, unscrew all the bolts for the timing chain cover (front block cover) and remove (sometimes with great effort), scrape away the old gasket, turn the engine until the marks are lined up, remove camshaft bolt, replace timing chain, replace crankshaft seal, rtv sealant and gasket everything up then put it back together. If I would have had everything I needed before starting I don't think it would have taken much more time. Prepping the gasket surfaces is what took the longest for me.

                      I've been meaning to do a write up on it... mushroom season kind of got in the way.

                        thats pretty much it. Balancer, crank pulley, and maybe 10 more bolts. Plus the gaskets under the cover of course.

                          Is't the balancer located under the water pump and not needed to be taken off?

                            it needs to be removed if you are replacing the timing chain. It prevents the cover from coming off. It does not need to come off if you are only changing the water pump.

                              One of my 88 CVPIs had 165K on it (double roller chain). It was surprisingly loose so I replaced it. Overall engine performance and gas mileage improved and also allowed me to switch the car back from 91 octane to 87 octane fuel without ping and the acceleration was better. These was replicated on a 1975 Torino Elite with a 5.8 Windsor when I replaced a loose chain and plastic gears. If your octane needs have increased or you had a slight acceleration lag, and especially doing a water pump or replacing a leaky front cover, DO THE CHAIN and GEARS.
