A rod knock will go away when the plug doesn't fire. Unplugging the injectors one at a time also works and is less risky.

As some may already know I have an 325i with 208k on the clock and a low oil pressure/volume problem which showed up as a lack of oil at the spray bar for the cam. I am replacing the oil pump on general principals (and praying that it works). Now that I have the new pump on hand I am figuring that the intake screen on the old one is clogged based on the tiny hole the oil has to flow through to get to the pump. At 200+k I am replacing the pump anyway. Of course the other opinion is that the bearings are all so worn that I can't maintain the oil pressure. As such I am suddenly very interested in what if any symptoms (other than lack of oil pressure) a worn out engine would give. - -- Joe - -- Joseph M.

Use a real pressure gauge to see >what is going on. > That is what I thought and why I am fairly certain that I have a blockage on the oil pump. I am not leaking oil, the compression is good, the rocker arms and valve springs are fine, I just don't have any oil left after it gets over the cam shaft. Now that I think about it I have noticed that (over a few weeks) the car went from crank engine, oil light out, engine starts to engine starts and then the light goes out a second or two later. I will know more this weekend. I have run out of things that I can check without pulling the pan (other than the pressure). - -- Joe, planning on real gauges soon. - -- Joseph M.

DexCool is an excellent coolant. Sulfate and silicate free and with a low pH level of 8.3. The coolant should be flushed every 2-3 years regardless of what some sales/marketing monkey might be blabbering. IMHO, anyone who believes that coolant should be left alone for 5+ years and 100+K miles fully deserves what's coming. > Brian Daley > 94 325ic (with Dex-Cool that's gonna get changed long before 100K miles) Same here. alex f '95 M3 and '98 328i both filled with DexCool as well as a mixture of Mobil 1 and RedLine lubes ------------------------------ End of [uucdigest] V3 #6274 *************************** | | In memory of Michel Potheau - friend, enthusiast, founder of the BMW CCA. |________________________________________ | Please visit these UUC-approved BMW parts vendors/service providers: | (listed alphabetically) | | Autoscope-Motorsports - http://www.autoscope-motorsports.com | |==================================================== | | Koala MotorSport .
