subridersix Posted January 15, 2011 Share Posted January 15, 2011 I have a 82 zxt donor car I'm tring to get running and I have a question about the turbo. The car has sat for 10 - 15 years. What should a good turbo feel like? I don't have any decernable end play but...when I reach into the compressor outlet and try to spin the blades it seems stiffer than I expected. It only freewheels about 3/4 a revolution . Is this normal? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 16, 2011 Share Posted January 16, 2011 Have you put some clean oil through it before trying to turn it? Quote Link to comment Share on other sites More sharing options...
subridersix Posted January 21, 2011 Author Share Posted January 21, 2011 I changed the motor oil with 10W-30 Castrol as soon as I hauled it home. It took me a month to get it running and I probably have a total of 10 minutes run time on it. The second or third time I got it running I let it run at about 1300 rpm for about 5 minutes. Other than that it's been a minute or so at idle while I try to figure my ignition issues. I have NO gauges (donor dash destroyed) so I'm can't tell what oil pressure is. Mechanical gauge should be here today and once I have that I can run the motor long enough to get it up to temperature. My Question: Is there anything I can add to the oil to help clear the turbo bearings? We used to use ATF for that sort of thing. I plan to run this oil thru the first high idle warm up and then change it. Thanks, Bob Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 22, 2011 Share Posted January 22, 2011 Seafoam in the oil. You may want to do the top end treatment too. Quote Link to comment Share on other sites More sharing options...
subridersix Posted January 22, 2011 Author Share Posted January 22, 2011 I've read a lot of controversial things about seafoam. Thanks, I'll check it out Quote Link to comment Share on other sites More sharing options...
softopz Posted February 7, 2011 Share Posted February 7, 2011 NO seafoam lil ATF in engine oil doesnt hurt change. Rad flush, vac/fuel hoses, air filter, plugs, wires here and there and should run like a champ! Quote Link to comment Share on other sites More sharing options...
