Recently my car had a slight shake to it. Had it read and it was a few misfires so i went and did my spark plug and coil change myself, didnt do it correctly brought it to my shop to have it fixed. They fixed it and a week later late night after work i was parking my car, out of no where my car started to shake really bad, it was so bad that i had to get it towed to the shop to have it checked up. Got it read and my mechanic told me there was misfires again so they put in new coils and spark plugs , still had the really bad shake, reason why he told me is that theres no compression going to one of the cylinders in the engine so i had to replace my engine. Estimate was 2,500 for used motor and labor. My original engine had 130,000+ miles. I'm thinking is this even worth doing and just getting rid of the car, need opinions. thank you

That’s for you to decide, we don’t know the condition of your car. If everything but the engine is in good shape (body interior suspension etc) and you like the car then why not? Or you could try something new.

Do you have any idea as to why you think your motor failed?

My car right now is pretty much in good condition, changing the engine and the fact that i got into a accident years ago makes the car pretty much unsaleable . thinking of just keeping it for now. for the cause of the engine being replaced is that the engine wasnt getting compressed correctly cant remember exactly what he told me but its along those lines. For the past few years ive driven the car very aggressively and rough and ive taken care of the car , did my oil changes , oil leaks, etc. ive seen engines go out at 30,000 miles. it just surprised me that it went out like that at 130,000, saw some engines go more than 200,000.

$2500 would be cheaper than to getting a new or used car IMO.

I would replace if everything else is in good condition.

Ask for 1) a compression test and 2) a leak down test they might just be pulling your leg without doing much work how trustable is this shop always get a second opinion $200 towing and diag from another shop is worth if it's going to save you $1-$2k

these engine can misfire for various reason it doens't always mean i'ts low compression.

if it's a 07/08 read up on MOSFETS

They did a compression test and thats how they found out about the problem. Im not really knowledgeable about compression in engines but if the engine isnt getting compression means the engine is bad? The shop is trustable i know the owner through close friends that know him personally.

Find someone to rebuild your motor.

If you blew your motor, you weren’t taking good care of it...

Very subjective question depending on followings: how good is the rest of the car? How much are you comfortable working on cars (older cars need a lot of maintenance)? How is your financial situation? Do you like the new BMWs ( electric steering and all)?

What were the codes being read?

If I were to get a rebuilt engine, I would look into MMP. For $3500, you get a lot of piece of mind and a few upgrades.

I only see N54/N55 listed, the OP has an N52. I wonder if they do those as well?

Yes and no. Could've been related to the cam ledge issue on early N52s, or simply a manufacturing defect. Pointing fingers won't really accomplish anything, the engine is damaged either way.

Rebuilding one of these will likely cost more than it is worth. They are fairly complex, and you basically have to hope and pray the person doing it knows what the heck they are doing. These aren't short block Chevys.

I'd trust a good used factory built engine over a cheap rebuild.

I wouldn't put 2500 dollar engine into a 10 year old car.

[08TUNDRA]

About 3 months ago I experienced very similar symptoms, Had zero compression in cylinder 4 and low compression on cylinder 5. Leak down test pointed to ring lands. I heavily maintained the car and honestly don't know what happened. It was just FBO with an mhd tune. Ended up buying a salvage car from the auctions and doing a manual trans conversion and engine swap. bought the car for 2k ended up selling around 4 k in parts off it so it was a small profit for me.

Am I wrong to think that $2500 isn't all that terrible? I've never looked in to engine replacement though, so I don't have a flying fuck of a clue what's normal.

Considering the alternative is to plasma-cut out the driver and passenger footwell and go Flinstone, I'd give serious consideration to the engine replacement

[BimmerNugget]

Not sure if I read that correctly but $2,500 is cheap as fuck for a used N52 motor plus labor to install it.

A used N52 with 70k to 100k miles already costs $1700 to $2000. The labor on an engine out procedure is billed at 12 - 15 hours of labor. So even at $100/hr labor thats another $1,200 to $1,500 to install it.

I'd say $2,500 for part & labor is a damn bargain and you should go for it! As long as the used engine has a warranty (90 days or something).

Time for an LS swap

1 - rebuilding the motor will be way more expensive than getting a used one. Not a good solution.

2 - lots of motors blow and almost always has nothing to do with the owner. Stress testing by manufacturers is incredibly rigorous and these motors are tanks sooooo it’s a manufacturing defect more than likely.

Also, you were banned. Why are you back Straight6?

Please leave

Idk. It's worth the call. They might be able to steer the OP in the right direction.

I dont know what i could of done for the engine to just stop working. I literally did everything myself and took care of the car as much as i can.

Cant do that , got a N52. Cant really remember the codes .

The rest of the car is perfectly fine, i do most of my DIY's except big things. Right now this situation just happen right when i finish school lol, new bmws (fx's) dont really please me with looks and performance.

I would look into a reconditioned N52. I would not just get a used engine. The guys at MMP may not have a reconditioned N52, but they may know of a company that does. It's worth the call.

How did the car perform after the engine swap? In my case , would my car still drive the same as before?
