Engine + Driveline / Re: Engine temperature has creeped higher over time
« on: February 15, 2021, 02:23:47 PM »
Just FYI,
Here we are several years later and my temp is still rock solid at 2 needle widths above center. I did change the temp sensor (in addition to all of the other parts I listed) with no change either. At this point I'm comfortable with the temp where it is and assume that it's just the new normal.
One other possibility is that I had a water pump shed its crappy plastic impeller a while back (a previous owner install), before my original post and I never did recover all of the plastic pieces. I'd bet that someday, when I pull the engine apart for a rebuild, I'm going to find a piece of that water pump partially blocking a water passage somewhere. As I said years ago, the temp is still in the normal range its just a little warmer than it used to be.
Cheers to all!

Maximillian appears to have one.
Might have to cut and paste.

Engine + Driveline / Seeking advice on noisy lifters
« on: February 15, 2021, 08:30:56 AM »
Hi all,
My 1991 318i convertible's lifters are getting noisy. It's got about 235,000 miles, the engine runs smoothly, STILL doesn't burn oil, has good compressions....otherwise still a pretty nice engine. I've had the car about 12 years and the lifters have always been noisy at start-up. They would tap for a few seconds and then quiet down. Over the last couple of years the tapping has gotten longer and longer now taking up to 4 or 5 minutes to pump up. Despite my wife encouraging me to replace the engine I still feel that it has some life left and I could probably get another 50,000 miles out of her (which at 3500 miles per year would be another 14 years....well into my retirement) if I just fix the lifters.
What's your opinion?
If doing the lifters, what other parts should I replace while I'm in there? ....such as timing chain and tensioner?
What special tools should I be looking for?
Thanks for your replies!

Engine + Driveline / Humming fuel pump pressure regulator
« on: May 13, 2018, 11:16:10 AM »
Hi all,
Thought I'd share something I just learned for those with a similar problem.
My car started to hum a couple of years ago. I was able to track this down to the fuel system as I could feel a definite vibration from just about any fuel line. I immediately thought it was the generic AutoZone fuel pump that I had recently bought for it so I quickly sourced an OEM VDO pump with no change whatsoever. (on a side note, when I removed that AutoZone pump I discovered that it too was a VDO pump!)
Nothing seemed to run badly so fixing the hum was not a real high priority, but by this spring I was starting to get annoyed by it so while ordering parts to track down some other problems I decided to replace the fuel pressure regulator.
Replacing the regulator is pretty easy and I replaced it with a BWD part from O'Reillys. Totally fixed the humming and I think it idles a little better now too!
Just food for thought for those out there with musical cars!
Regards!

Alex,
Thank you for your reply. I'm quite certain that I'm not leaking coolant but thank you for the offer of your coolant pressure tester....very kind!
The temperature behaves as if it is being regulated at the 2 needle widths position by the thermostat. If I were running out of cooling capacity (thermostat fully open) I would see the temp change going up hill and down hill, or change when stopped at a light vs running down the road, but it is quite solid during all of these different times. Replacing a partially blocked radiator like I had with a new fully open one would have certainly caused a change in behavior and I had loose wires on the fuel and temp gauges when I bought the car 9 years ago (I believe the seller sold it to me cheap because the temp gauge would sail into the red after a couple of minutes because of a loose wire.....something he did not disclose) but the gauges were erratic and not steady as they are now with tightened nuts.
I'd check temps with my laser thermometer but I do not know what temp corresponds to what marking on the gauge itself.
I think the next step will be as you suggested, replace the sending unit.
I'll be back!

Well not so fast.......
Driving to work, a 1 hour drive on the hwy, engine temp returned to its previous 2 needle widths location. In addition I discovered a leak on my radiator at the base of the expansion tank. I removed the radiator then removed the tank to discover a crack in the plastic base of the tank so I purchased a new radiator and disassembled the old radiator.
Mind you I use dexcool mixed 50/50 with distilled water and change every 4 years. I’ve done this for 20 years or so with terrific results so I’ve never suspected my radiator would be anything but in the condition it was in when I purchased the car 9 years ago. Attached is what I found when I pulled one of the tanks off. I have no idea what the deposits are. It brushes off easily with a finger and for all I know has been there since I bought the car.
Needless to say I thought I had discovered the cause of my warmer temperature. I installed the new radiator and took her for a drive and.......no change in the temp! STILL 2 needle widths above the center.
So to recap I’ve changed all the hoses, the thermostat, the fan clutch, the water pump and now the radiator with NO change in the operating temp of the engine. Either my engine is running hotter for some reason outside of the cooling system or my gauge/sending unit is at fault.

Changed the fan clutch and we’re cooling much better! Not quite back on the center line of the temp gauge but running down the highway it’s just a hair above the line.
I bought a clutch from O’Reily’s and is says made in China so we’ll see how long it lasts.
Thanks for the advice!!!

Monty,
Thank you for your reply. The temp is rock solid at the one to two needle widths above the center mark whether sitting at a light or running down the highway. It will cool off a little during extended idle.
Thanks again,
Bob

Engine + Driveline / Engine temperature has creeped higher over time
« on: April 20, 2018, 08:28:39 PM »
Hi all,
I've had my 1991 318ic with M42 for 9 years and have kept things running pretty smoothly just reading posts on this site. However I have not seen a post of my issue exactly so I thought I'd throw it out to those here with experience.
My normal operating coolant temperature has been creeping up ever so slightly over the last year or so. Right now when running down the road at highway speeds it is about 1 to 2 needle widths above the halfway mark. Although this is still in the normal range I don't really like seeing it there since for the last 8 years it was rock steady on the halfway mark. I've got just under 220,000 miles. Over the winter I replaced all hoses, water pump, thermostat, belts and a slew of other parts with absolutely no change in the temperature. I have no coolant in my oil or oil in my coolant and my compressions were 185, 187, 185 and 186. The gauge is rock steady so I do not suspect a loose ground or other wire.
My gut says change the temp sensor but wanted to check with the experts before I do just in case I'm missing something.
