Default need an engine, info related to same

New to this forum. Hi guys, treat me gently please. I'm sensitive. I have an '02 Montero Limited. Drove it this past winter at 16 deg F with the coolant frozen. It did not survive. Cylinders are zero compression. It has sat since then. It was burning oil anyway so I would like to just drop in a good used engine. I have looked on ebay and www.car-part.com and they are both real proud of their offerings, $2k and up for 100k+ engines. I see Diamante 3.5L engines for $650 with 50k on them. I guess what I am looking for is 1 - sources for an engine, 2 - The info needed to get the right engine. What engines can I use? Throw me a bone y'all, anything I need to know would be appreciated. The truck is in good condition and I hate to part it out over an engine but...

Thanks in advance.

Talking

Have you tried local junk yards in your area? That would be my starting point. Probably where you'll find the best prices as well. And you could also look on craigslist.com as well.

Pull the engine out and see what damage was done. Frozen coolant should have popped a freeze plug, but it may have not. You might of cracked a head or popped a head gasket. It might be worth it to just rebuild the engine if the damage was minimal. Worth a shot.

Default Replacing a Montero engine

He does have a great question. Other than the Montero, which other Mitsubishi models use the same engine? Would a 3.8l engine from a newer Montero also work in his application. Is there any source for this information? This is something that I'd like to know for future reference.

Alas, it was not meant to be. One head and the block are cracked. That engine is junk. The Montero is now parked out behind the barn collecting bird poo. It was a nice vehicle and I miss it but lacking any kind of viable engine replacements at a reasonable cost... it's a junker. I can snag good 3.5 engines from same era Diamantes for $400-ish. Nothing out there for the 02 Montero that ain't presumed to have solid platinum pistons and a price to match. At some point I may roll it in to the shop and break out the torch. See if I can make enough room in that engine bay to stuff a 302/351 sbf or a Chevy 350 in there. Turn it in to a 2wd sleeper. Or just let it rot.

Billy C, welcome to the forum. Sorry to hear about your solid coolant adventure.

I'd hate to see your Montero turned into a birdbath for want of an engine. Here's some info from Wikipedia:

6G73

The 6G73 displaced 2497 cc. It was a 24-valve SOHC design with 2 valves running off one cam lobe, with a smaller bore than the 3.0 liter version of the same block. Bore and stroke were 83.5 76 mm (3.29 2.99 in); it was a 60-degree V6 and weighed around 155 kg (340 lb). The engine had low-profile cast aluminum heads which helped it to fit into small engine bays, while pent-roof combustion chambers increased efficiency and made room for four valves per cylinder, arranged in a cross-flow pattern with a "tumble" intake port for both strong breathing and low emissions. Spark plugs were centered in the combustion chambers. The intake valves were 33 mm (1.30 in) in diameter while exhaust valves were 29 mm (1.14 in). A toothed timing belt was used. The output of 6G73 was 161 hp (122 kW; 163 PS) at 5900 rpm with 221 Nm (163 lb-ft) of torque at 4350 rpm.
Applications

6G74

The 6G74 is a 3497 cc 24-valve unit available with either SOHC, DOHC, or MIVEC DOHC. Bore is 93 mm and stroke is 85.8 mm. Output is 153 kW (208 PS; 205 hp) at 5000 rpm with 313 Nm (231 ftlbf) of torque at 4000 rpm for the SOHC, 194 kW (264 PS; 260 hp) at 6000 and 324 Nm (239 ftlbf) at 4500 rpm for the MIVEC. The most common 6G74 has a cast iron engine block and an aluminum cylinder head. It uses MFI fuel injection and uses forged steel connecting rods.
The gasoline direct injection version of the 6G74 was launched in April 1997 as the first GDI V6 engine ever produced. It differed from the basic 6G74 in many ways apart from its unique fuel injection system — it had a crown-curved rather than flat combustion chamber, upright intake ports rather than angled, and a 10.4:1 rather than 10.0:1 compression ratio. Mitsubishi claimed 30 percent better fuel economy, a 30 percent reduction in emissions, and higher power outputs than diesels.
Applications

I would think that East Texas would be brimming with opportunities for finding cheap engines, but maybe that's just a Californian's idea of an idea, like you all have pet steers in your backyards and eat barbecue three times a day.

Anyway, I like Manda's idea of finding a low-mileage junker and putting that in. That would be the most cost-effective option.

These guys are good, but I don't know if shipping makes it a deal-breaker for you:

Try and keep your beast on the road — these are really great vehicles! Either way, let us know what you decide...

Here's one in Raleigh with 160K. There should be others out there - hopefully closer to TX and with lower miles - willl send links as I find them.

Bingo! - (Maybe)

Unless this is one of the "Platinum Plated" pricing guys, here's a good sounding engine pretty close to you:

Default I'm a Newbs too,....

However, I just relived the same scenario. My 99 MS lost oil pressure, I suspect to faulty oil pump...the result was a FUBAR engine. My MS sat for 2.5 years until I squirreled away the resources...I looked everywhere, including all the sites mentioned herein,...Until one day I was told about Japanese exports...Apparently Japan has some weird taxation plan for all vehicles the exceed a certain mileage...As I was told, the tax is quite cost prohibitive, making new cars more appealing and therby creating an export market.

I recently purchased a 3.0 ltr. for my MS with 35K, clean as a whistle, shipped across the pond and then across the country, dropped directly to my mechanic and installed without issue. Turn key I believe I put 2K into this project and I now have my MS back and better than ever. I'll include the link. This company is top shelf, great customer service before AND after the sell....

Good Luck!!!

JB

Thanks for the link, Dawg.

And they have my engine, just in case I need one one day.
