Hello

I found a rb25det at a used car parts store, its been there for about 6 months or more.

The staff doesnt know if it runs or not.

They only test they did was check to see if the crank turns and take a look at the gears and things underneath the front gear cover.

Is there any way to check the engine besides taking it apart to see it maybe its working or not?

I wouldnt be able to take it apart unless I buy it

Have a beer with it and ask if it's ok

The shop is a well known shop. Anytime they get something that they dont know about, they put in the junk section or reduce the price to a cheap price. If somethings in the junk section, doesnt mean doesnt work, just mean pieces missing, old, or no information on it.

They will usually put whats wrong with something or what condition it is in on the label. Dont think its in the junk section.

This engine they dont know if anything is wrong with it. They did the checking I mentioned earlier.

Not sure if it has their normal one week garuntee on it. If it does, there is no why I can have it put in the car in a weeks time.

Its 650.00 dollars

$650 is basically scrap value for an RB25. That's what you pay for one that is or could be broken so that you can use some or all of the parts to fix another one. A good runner here is more like $1500. So it is not a bad risk for you, and you might be able to break it up and sell parts if you were forced to. But you'd be committing to trying to use it unless you do the minimum testing, like a leakdown and see if it will crank and so on.

Ok

So that means pistons, chambers, valves etc could be messed up or they may not be. Hmm I have to decide if I am going to take that chance. Would buying a working rb25 and building it up be better than buying one that may have to have more parts replaced? Or will it be about the same if I am going to build up the engine?

Car battery, jumper leads to the starter motor and compression test it.

Then compression test again with 5ml of oil in each cylinder and record results

If they're all equal with a delta of 10psi between each cylinder then it will be fine.

The engine should still come with around 3 months exchange warranty, regardless of whether they have seen it running or not. Unless things have changed.

He is in Japan.

Crazy shit applies there.

    • Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.
    • Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.
    • Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.
    • It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.  
    • Careful with posts like that around here without the flame suit on @cobo_11! 😂😂 My 330i journal is on here too. That car was so good and super reliable. We still have a 130i in the family which is almost identical to the 330i and easier to find in manual. It has also been almost faultless over the 6 or so years in the family.  I used to want an M car a lot more than I do now but if I'm honest and without trying to sound like a wanker, I can get such good performance and handling out of my 335 without needing to worry about all the crap that goes along with M car ownership. I don't need to worry about my bearings or subframe issues or the cost of replacing brakes or suspension or whether it has been impeccably maintained. And I can leave it places and not get upset when it's always filthy.
