Keep Sinking Money or New Engine?

[4.8isX5]

So you need valve seals done then...

How long have you owned the car? Valve seals is a common issue, what i would take into account is that if youve been keeping it up properly or had it for longer, its better to just do the seals ans invest in the engine that you know. You wont know a used engines history, the owner may have changed oil every 20k miles and will have more issues down the road.

Not only that the labor on pulling and installing a new motor will be more then this.. Im not sure which method your mechanic is doing and if he is pulling the heads or not, but it can be done now with the valve seal tool from AGA which simplifies it even more by just removing valve covers/intake and doing the seals that way. Valve cover gaskets and seals cost for parts is total beans $.

I was thinking rebuilt:

Like this one on Ebay

Saw a couple other options for $3,500 or so.

I have only had the vehicle about a year, but it has great service history with oil changes done on time at the dealership. If I recall correctly, it was a lease that was then purchased.

"New" engine won't solve the problem because you still sink money into the valve stem seals!


1. Best option is dealer tech working from home. This fellow is from Long Island NY and charges $2500 for it:

2. If you DIY, then it is mostly parts, labor is yours:

If the original owner leased the BMW and maintain it by BMW's schedule that means the oil was changed every 15,000 miles. Most leases are written for 10,000 to 12,000 miles a year, so if the lease was for three years and he max out on the mileage of 12,000 per year the oil was change only twice.

And BMW will not provide oil change every 3,000 or 5,000 miles as part of their free maintenance program. Perhaps that is why valve stem seals are failing because the oil after 15,000 miles loses some of it's lubrication property and additives to keep seals pliable.

I don't know what a timing valve cover is. That is what the OP stated in his first post.

The current problem is that there is a slow leaking that is hitting one of the spark plugs. I can't remember which seal it is, but the mechanic said it would probably cost $5-6K due to labor.

Would it make more sense to have the work completed in light of the repairs we have already made, or should I purchase a remanufactured 4.4 engine? I have seen a couple on EBay for $3.5-4K including shipping and come with all the needed gaskets, thermostat and water pump.

What would it cost to swap the engines? Would a new engine be too much power for an older transmission?

Thanks in advance!

Don't think the original poster is a mechanically car savvy guy. He didn't notice the blue smoke while inspecting the X prior to buying it. This condition didn't just happen over night. Another reason why one should get a PPI by a reputable mechanic before buying a X or any car that is expensive to repair.

And people on this board criticize me, when I tell a NOOB that if they aren't a DIYer and the car doesn't have a warranty a used X is probably not the right car for them.

Given the owner current situation it would probably be best to drive a few hrs and get the job done by the BMW tech, while he is there get other common engine problems taken care of. This seems the most inexpensive option

4.8isX5 – Good point on knowing the engine history, at least we now know all the gremlins, and have had all the work done by the same guy.

cn90 – Thanks for the links, the DIY certainly was illuminating, but outside my scope. I will definitely look into the home mechanic!

upallnight – Interesting insight on the lease practice. I will have to double check but it looked like oil changes were done at 3,000 mile intervals, or very close to that.

trader4 – I saw one rebuilt engine on Ebay that comes with water pump, all gaskets, and a thermostat. What else would be routinely replaced/needed when swapping an engine?

Motorsport1207 - I am starting to lean towards that option of the $2,500 home mechanic, but am wary of no business insurance or warranty on work (making assumptions here).

Before I purchased I actually took the car to two different mechanics for a PPO, both indy’s, and one of them was a BMW specialist/former service center guy. Nobody saw the smoke! When we took it to emissions testing it plumed smoke, very inopportune timing, but didn’t happen again for a while. Honestly we don’t get much smoke at all, maybe every other month or so.

Right now the problem is that after a spark plug gets fouled she starts running very rough when idling or at low speed, otherwise I wouldn’t worry about. From my research before purchase it just seems like this vehicle is prone to leaking oil, which I can live with. We also went in knowing this car is expensive to maintain and figured that into the budget, just didn’t know how much valve stem seals cost at the time!

Question:
If we keep the car and do the valve stems, what else should be replaced at that time for longevity/ease of access since the engine is torn apart?

Thanks again for all the help and insights, I know I will make a better informed decision because of all of you!

Here's an excerpt from the current BMW Free Maintenance Program to all new owners.

Exclusions from coverage include the following:
Items reimbursable under your New Vehicle Limited Warranty
Gasoline and diesel fuel
Gasoline and diesel fuel additive
Diesel glow plugs
Diesel particulate filter
Windshield washer additive (except when in conjunction with scheduled maintenance)
Tires, wheel alignment, tire balance and rotation
Parking brake shoes/linings
Reset Tire Pressure Monitor
Wear and tear of soft trim items, such as: seats, carpets, moldings, headliner, door panels and all chrome trim
Damage, including consequential, which results from negligence, improper operation of the vehicle, wear and tear or deterioration due to driving habits or conditions, improper repair, environmental influences, flood, accident or fire damage, road salt corrosion, alteration, installation of non-genuine BMW accessories, or use of improper, poor quality or contaminated fuel
Altered or unreadable Vehicle Identification Number (VIN) or odometer irregularities or vehicles where the true mileage cannot be determined
Maintenance or repair after the vehicle is deemed a total loss
Maintenance or repairs performed by other than an authorized BMW center within the United States or Puerto Rico

Vehicles used in competitive events
Oil changes performed outside the recommended maintenance intervals as indicated by the Condition Based Service
Any other vehicle-specific exclusions described in the Service and Warranty Booklet included with the vehicle

If you look at the oil service indicator light I bet you it won't be going on at 3,000 miles between oil change.

@X5DC,

The home mechanic (actually the guy is a master tech at BMW dealer) option of $2500 is a good deal, IMHO. This job requires tools, expertise and many back-breaking labor hours.

Look at it this way: budget $3000 ---> $2500 for the job and $500 for a trip to NYC, which is about 4h drive from Washington DC...

- PM the master tech and arrange a free weekend.
- Let's say drop the car very early Saturday AM, such as 8AM. Leave your house at 4AM...lol..
- Go and enjoy NYC, concerts, dinner, sight-seeing on a Saturday night.
- By Sunday afternoon, the car should be ready.
- Ask the home mechanic if he can give you some type of warranty.

Just read that thread that I linked on the previous page.

$3K for this car is worth it because once this problem is fixed, the car will be fine for another 100K w/o valve stem seals issues.
