Life span of a 3.4L

Well when I brought mine it had 15800 then I look at carfax in 2017 it had 32000 so as of now the miles is anyone guess. It has 17600 on clock. So if anyone can figure it out please do tell. I got engine coolent leak fir manifold today.

 

323k on my 1998 and still truckin!

 

I guess the bottom manifold gasket leaking coolant. Where is there a good place with prices for the bottom gasket please

 

My 2000 Tacoma has 485000km just services them regularly and will run for ever. We have a 2000 Camry has over 700000km

 

1996 with 308k, runs like a champ!

 

2002 4x4 with 165k just blew my second one yesterday, 6k on the new engine and boom 3rd times the charm right?

 

95 with 213k still runs strong

 

Mine went out at 130k . Motor ran for 17 years so longevity was there . I was the 3rd owner .. I put a new oem short block ...hoping I won’t have to buy a new one for another 17 years

 

2002 w/180k (give or take) and still runs like a champ.

 

how much money did it cost yah?

 

My 2001 3.4 V6 Prerunner is at 308,000, but it's required some love. The guy who dumped it on me regularly towed at its capacity, which I believe led to some of the issues I'll mention later. He did change the struts and coilovers, radiator, upgraded air intake. When I got it, the only obvious issue was leaking valve cover gaskets, concurred upon by a mechanic I took it to for a pre-purchase inspection in the town where I bought it. The previous owner claimed he'd done extensive maintenance, and that "there may be some minor cosmetic issues, but you couldn't ask for a more mechanically sound first gen taco".
So far I've replaced the passenger door handle, driver's window motor, xtracab window latches, passengers' headlight, all exterior bulbs, some arbitrary rattles, battery, fuel filter, brake pads, brake fluid, engine and transmission mounts, engine oil and oil filter, whole rear diff/axle assembly, steering rack, sway bar links, and ball joints. I also did the driveshaft carrier bearing and u-joints as formalities. I still have to do the front lower control arm bushings and now that I've changed the rear diff it's obvious that the transmission's an issue too. Call me crazy for doing all this maintenance at such high mileage but I can guarantee that the engine is pristine; my friend who is a Toyota mechanic came by and confirmed this when I was doing the VCGs (not the mechanic who missed all the initial red flags). I feel like I'm too deep now to quit so we'll see where things go Besides, cars are in such short supply these days because of the supply chain issues so I've been more able to justify fixing the thing up.

 

got 300 out of 2 diff trucks. have one currently with 260 and I bet the sh!t out of it... Change the oil and they last for a while. Oh yeah, keep a clean air filter too.. NO filters with OIL!!! kills the rings!

 

why would k&n filters kill the rings?

 

1989 22RE 4wd, 184,xxx mi.
still fresh (;

 

I mean, Im not 100% sure that it was the cause but I just bought a 2004 with a bad motor and the intake and throttle body was caked with oil and sand basically... The k&n filter was in the truck still and it looked like the kid just kept oiling it instead of cleaning it... Anyway, the cylinders had like 30, 60, 90, 110 compression and when I pulled the motor and checked the valves they were totally fine.. I did the oil test and it brought the compression up to 130-140...

So, I basically decided that the sand that escaped the filter with the oil ruined the motor....

 

318,000 miles and counting on my 4x4, 3.4 '96 SR5. If yours is a 4x4, I'll buy it from you today. 65k is barely broken in.

 

My dad had a 93 Toyota pickup over 450000 before it was stolen and then bought a 2003 Tacoma and got it up over 400000 before someone blew a red light and jackknifed my brother in an accident 2 years ago. Other than maintenance my dads never replaced an engine or replaced the clutch as far as I know.

 

Uhh the guy who had mine before installed a K&N oiled filter... what do I do? Stop oiling it and just clean? Change back to stock intake?

 

182k on my 03, hoping to double that!

 

Get a dry air filter like the AEM Brute filter if the diameter is the same, you may want to verify
