high mileage engines

[kad5118]

For the gbodies that are out there that have only 200,000 miles on the engine and are still going hard.what do you guys do to keep those motors going strong with all those miles

my buick v6 has about 40 after rebuild but one would assume that regular preventative maintenance would keep up going for a very long time.

HO oil pump for piece of mind but keep that oil changed and a decent filter and oil

My old '79 Malibu wagon had over 225K on it when I finally parted it out.

All I ever did different was run some heavier weight (HD30) oil in it during the warmer months...

My gbody doesnt have that many miles, but We have a couple vehicles with around 190k miles. Keeping the oil & filter changed is the main thing! Keep the fluids topped off & check them regular as well ! As long as you keep the oil changed & check it & all the fluids regularly, change trans fluid & coolant when it needs to be, they'll last a long time. Also, Change the rear end lube every few years too if you run them as a daily driver. Dont forget to change the air filter when it begins to look dirty. Keep the front end & driveshaft Grease fittings greased up. If you have any doubts that the differentials leak, check on them periodically. Replace belts & pcv valve every 30k or so. I generally run a slightly heavier oil, such as 10w40 instead of 10w30 when the mileage gets up there or I add a 1/2 quart or so of Lucas

I broke my 305 down last spring for a cosmetic overhaul. My grandfather was the original owner and it'd never been apart deeper than the valve cover gaskets. He was pretty fanatical about oil changes. Since he bought Delo400 by the drum for his log truck, that's what was used in my Cutlass since day one. I was really impressed with how clean it was inside. Even at 160K it doesn't smoke or burn any oil at all. I'll keep feeding it Delo since that's what it seems to like. Inside:

I got 238,000 out of the original 350 in my 78 El Camino.I was driving to work one day and the ft lobe on the crankshaft just snapped off. Got about 20,000 on the new engine. Both have had nothing but 10 W-30 Mobil one.

Ive got 69,000 showing on My five digit counter. I'm assuming its really 169,000 lol. I just change the oil reg top off all fluids buy good parts and don't hot dog the tired engine. Pretty soon will be draining the rear and Trans to replace the oils.
