Hi; THis is from the Alldata website. I have a subscription and was reading up on emmission controls as mine are half removed and saw this. Hope it helps: High HC & CO - at High RPM This condition is indicated by abnormally high carbon monoxide AND hydrocarbon emissions during cruise (2500 rpm). POSSIBLE CAUSE ACTION Electrical misfires Check ignition system Vacuum leak Check vacuum lines and routing in "Vacuum and Vapor Hose Routing" in Emissions - Check intake manifold and vacuum components Faulty bowl vent/canister purge system Check Evaporative System in "Testing Procedures" in Emissions PCV malfunction Check PCV system in "Testing Procedures" in Emissions EGR malfunction Check EGR system in "Testing Procedures" in Emissions Restricted exhaust Check Catalytic Converter in "Testing Procedures" in Emissions Initial timing incorrect Check Ignition Timing in "Adjustment Procedures" in Emissions Incorrect Spark Advance Check Spark Controls in "Fuel Injection and Computerized Engine Controls" Verify vehicle remains in Refer to "Fuel Injection and Closed Loop at steady throttle Computerized Engine Controls" for (2500 rpm), oxygen sensor operation is working Self-Diagnostic procedures Fuel metering malfunction Carbureted Check carburetor passages, bleeds and restrictors, internal leaks, float level, metering rods and gaskets Replace or rebuild if faults are found Fuel Injected Check fuel pressure Perform injector balance test Test regulator operation (check vacuum line and return hose), Service Fuel Injectors (pressure clean) So I see the formatong is COMPLETELY messed up. This sholuld be in two columns, hopefully you can make sense of it.

I have posted a couple of times on here about the TOD on my 86 GL wagon, which is now nice and quiet. The cure? New gaskets on the oil pump + replace the impeller (2 pieces) and the seal on the impeller shaft. This was less than $50 Canadian, as compared to $344 I was quoted by a dealer for a new oil pump. Cheers

OK, this is going to make me insane. For the second time I thought I had the noisy lifter problem beat and it has come back! I cannot for the life of me undertstand how it can go away for days and then come back as just as bad if not worse. Quick Summary: 86 GL Wagon 200k km 5 speed dr 4x4 Looked at car prior to buying it two weeks ago. Lifters were noisy but cam cover bolt was missing so I figured that would fix it. Car is generally in good shape and seems well maintained. Replaced bolt and it was great for two days around town. Drive 300km on the highway and the noise is back. Looks like the oil got inadvertantly overfilled, consensus is that oil pump seals need changing. Change oil pump seals, sure enough the old ones were flat and hard and noise is gone, again for two days around town. Drove car 300km today and it's back. Arrrrgghhh. Oil is fresh W10-30 High Mileage Castrol. Oil pressure looks good to me. 3 kg/cm3 - 5 kg/cm3. Oil pump seals are new. Engine seems to run fine although down on power compared to when lifters are quiet. My next step will be to replace the pressure relief springs and o-rings in the cam holders, but I'm a bit baffled. This would make sense if the previous attempts had not worked, but they did...for a while. Does this sound reasonable, or am I missing something? Roger Frustrated, but still loves his Sooby Doo

So now I have the lifters quiet I notice that I am leaking a fair amount of coolant. It's hard to see where it's coming from but it appears to be from the bottom of the waterpump. Doesn't appear to be from the weep hole, but further back. Car has 200K km, so I should probably replace the waterpump right? Or am I missing something else common to these cars?

Replaced the oil pump seals, kind of an ugly job, and I had to redo the timing belt install, but all is quiet now. Also reconnected the vacuum advance to the distributor, and set the timing, so it also runs better! Thanks for all the advice. Roger 86 GL Wagon 4x4 Dual Range

Hi All; So I just bought a 86 GL Wagon with about 200km on it. When I was inspecting it I noticed that the lifters were very noisy on one side, but the vehicle was otherwise in great condition. Upon further inspection I noticed that one of the rocker cover bolts was completely missing and it was blowing oil out the hole. Aha, I thought, this would lead to low oil pressure and hence noisy lifters. So I bought the car drove it home, replaced the bolt (free from friendly local dealer!) and congratulated myself on the now much quieter lifters. That's when everything went horribly wrong. I then added a can of Wynn's something or other (said it quietens noisy lifters) and went to bed. This morning I drove 300 km to where I work during the week and holy crap, the noisy lifters are back. Hmmm I thought, maybe the Wynn's stuff is causing a problem, let's dilute it by added some fresh oil. Still no better, OK lets run by Mr. Lube and just get fresh oil. That is when I discovered that there was almost DOUBLE the correct amount of oil in the motor. So the previous owner probably added extra to compensate for losing oil through the missing bolt hole and then I added the Wynn's AND more oil and here we are. Talk about your self-inflicted injury! So after I finished kicking myself in the ars* repeatedly I started reading about "Tick of Death". I'm assuming at this point that I have damaged a seal or two somewhere, but I would like to know where I should start. It seems like the o-ring under the cam towers would be a good place to start, but I can't tell from the write-ups if I have to remove the timing belts to get at this. Anyone have any experience at this? Any other ideas would be welcomed with open arms. btw, oil pressure is good, it is on the 3 (kilo pascals or whatever, 1/2 way anyway) at idle and 5 (5/6 of full range) at speed. At this point the lifter noise is pretty bad, kinda reminds me of the old air-cooled VW's. Am I damaging it by driving like this? Cheers Roger
