M20B25 offer without warranty frm a junkyard..good?

[nsbone_1988_520i]

Hi,
I have an offer an M20B25 (motronic) engine just the engine block with internals and head for RM1800 (US$460) with warranty or RM1200 (US$310) without wrranty.

From the outside, the engine looks pretty ok. I have yet to open the oil cap on the head and see if the cam is reasonably looks good.

Question:

• How often M20B25 frm a junkyard (scrapped 525i imported from Japan) can go bad?

• Would i take too much risk, as i could loose the USD310 for nothing? Or is the risk is worth it?

• or i should spend the additional US$150 for warranty/replacement if the engine block/head could be a bad one...

Appreciate for any opinion...

For 310, I don't think you have much to loose. 150 is a lot of money for the warranty. Maybe get a mechanic friend to come with you and look it over.

Are there wrecking yards in Malaysia close to Johore Baru? I will be in Singapore in a couple days and would love to get a set of euro headlights off a care there.

Actually, does this car you are pulling from still ahve its full headlight assembly? If so I'd be interested and would pay you to pull it and ship to me in Singapore.

the m20 is generally a tough engine and as long as it's seen a few oil changes and the belt doesn't break you can get well over 200k miles without any problem at all. mobil one (the oil company) did a cool test many years ago, they took a brand new 87 325ism and put it on a roller dyno and ran it in real world type conditions with all synthetic fluids, the tranny died around 600k miles and they tore the motor down at 1,000,000 miles and it was still in factory spec on all surfaces, i can't remember how much further they ran it after reassembly, it was several hundred thousand more miles before they gave up trying to wear it out
