155800 Miles "tune Up"

[Jamez]

Two days ago I recently did a Inspection/Tune up on my bimmer. It was my first time working on the vehicle engine wise since the purchase. Currently it has 155800 Miles on the engine and when I first purchased it, it had 150100. I was 3,200 miles overdue of oil change. Ok anyways here are the tunes ups performed on my bmw 325is 1993.

Jan 10, 2005
1: Oil change :Mobile 1 full synthetic oil 5w30: 7 Quarts
2: Replaced Oil Filter :Purolator: 1 Quantity
3: Replaced Air Filter :Purolator: 1 Quantity( AutoZone&PepBoys didnt have K&N Air filters in stock)
4: Replaced Spark plugs :Bosch Platinum +2: 6 Quantity
5: Filled Gas Tank with Valvoline Fuel Injector Cleaner

Ok, I know this aint much of a tune for the mileage of my car but thats why I need to know what else should I tune up? Its been 3 days from the tune up and the car has been running alot better than before.

You may want to change the fuel filter, microfilter and rear shock mounts. Also, check the guibo disk and check your exhaust system hangers. What about a brake fuid flush and changing the fluid in the diff and tranny.

Keep an eye out for oil leaks from the synthetic. I wanted to switch to synthetic but I am doing it in phases to minimize any leakage..and very important absolutely change the tranny and diff fluid. Fresh fluids can be the difference of a very costly tranny replacement

I didn't think that would help, however I don't want to hijack the thread so I'll stop there.

The other things you can do are check gaskets, hoses, compression test ect... This will give you a fairly good idea of how things are going and what you might need to be planning on doing.

Doing the oil switch gradually is for my preference. I saw on here that it's wise to do it in stages on higher mileage engines just in case a leak developes I can revert back and hopefully minimze the leakage before its too late.. You think this is incorrect? I want to know if im doing something wrong..

Thta's what I am doing with mine. It had 169k on it when I started to make the switch. Many people recommend using an engine cleaner, but I am not a fan of any of thos "magic" substances, e.g., engine cleaners, gearbox enhancer, radiator cleaner, etc.

u changed the spark plugs and not the wires??? u should get them changed also!

hmm.. yeah I suppose that would work, it would take a while to do properly, but I would think that the oil would not be as effective, but before I say more I will have to check up on the density of synthetic vs. non-synthetic, but in theory it would work if you only used a little synthetic and changed your oil every 1000 miles or so and used a little more synthetic each time... but in the mean time I would be a little worried about the effiectiveness, I would also have to know if it would simply create a synthetic blend ie, how the oil would mix, but if it did mix to creat a blend why not just use a synthetic blend instead of mixing synthetic and non yourself?

okay I see our confusion, I am in fact using castrol sythetic blend. I wouldn't recommend "mixing" the blend yourself, but who knows it may work... I plan on 2 intervals with the blend and if still no leakage then make the switch to full sythetic..

[Jamez]

No leaks yet with the full synthetic oil. Oh btw someone recommended to replace the spark plug wires too... how do I do this.

Ok, that makes a lot more sense, that should work, but keep in mind that switching to the full synthetic may still cause leakage, beacause there are still sediments in the sythetic blend oil that may cause the blend to not pick up enough of the sediments of the previous oil to cause a leak.

It really is quite easy, you shouldn't have any problems here is a DIY

It also has a link in it for a DIY with pics. It is reccomended that you stick with the OEM plugs, some people have problems with other ones.

I said WIRES not the spark plugs... or did I miss something..

[thekid]

I believe that is in the pelican parts DIY... but according to the DIY you can not change the wires... If interested in why read on.

you could clean out the engine by adding 1/2 to 1 quart of tranny fluid in your oil system about 500 miles before the next oil change. i got that tip from a bmw master tec. worked for me.
