oil pressure on 77 gl 1000

Hi fellow goldwing people, Im sure someone can tell me what oil pressure I can expect to see from a 77 gl1000 with 90k miles on the clock and 100 pound average compression on all cylinders. I am also interested to know what sort of oil consumption some of the high milage wings have, mine drinks about a pint of oil every four tanks of gas. Thanks

My '77 Gold Wing was never down more than a pint of oil in 3,000 miles. Assuming you fill up when it goes on reserve, that would be around 150 - 160 miles. Four tanks of gas would be about 600 - 640 miles. Your consumption would equal about 1 quart in 1200 - 1280 miles. That seems like an excessive amount of oil use to me.

I did not have an oil pressure gauge on mine, never needed one.

I agree with you ,it is excessive, I read in the clymer manual I should be giving it a recon as the compression is so low and judging by the oil consumption the rings must be past their best mileage. It still starts and runs really well and 100 mile per hour is no problem at all, It is just coming out of winter here so a recon is out of the question for some time. Thanks for your reply

You can connect a oil pressure gauge to the engine where the oil sensor is located, toward the engine centerline toward the rear and right side. 100psi is low but more importantly it's the difference between cylinders that counts. If all the cylinders are within 3-5psi of each other the rings are probably okay. The actual reading of pressure varies a lot since the cranking speed of the engine has a major effect on the maximum pressure developed. Because of that a weak battery, poor electric cabling, burned starter relay contacts and a poorly performing starter will all have an effect on comrpression pressures. The test should be made on a warm engine with the spark plugs out and the throttle and choke wide open. A closed throttle or choke will make a large difference too. The most common cause of oil consumption are the valve stem seals. I'd change them first before going any deeper into the engine, that may be all it needs.

Thanks for that exavid I will check stem seals as you suggest as a recon isnt going to happen till next winter anyway.

Usually if the stem seals are worn, you will have a lot of blue smoke at start up. Especially if left on the side stand.

Do you have that?
