411 on Used car tips
Well RX7's as I know are turboed. Well I have created a FAQ on car buying Tips so here it goes. This goes for any car Nissan,Mitsubishi, Toyota etc.
-Stay away from High-mileage cars (in some cases go for it). Ditto cars that have already been heavily modified, so you don't have to worry about the quality of someone elses work.
-Check for oil leaks from the Turbo. If you see blue exhaust after the car has been warmed uup, chances are good there is a leak in the shafts. Another way is to disconnect the pipe from the compressor and wipe inside.
-Another oil ip; Since oil is the lifeblood of your engine and the turbo, check the condition of the crankcase oil. If it looks dirty or needs replacing, it might be a sign that the previos owner didnt take good care of the car.
-Pull off the compressors inleft pipe and check for foreign-object damage to the wheel blades. This is especially important if the car;s air filtration system has been removed.
-With the inlet pipe disconnected, reach in and sping the shaft. It should turn easy. Pul back and forth and up and down on the shaft to make sure the bearings are stil healthy.
-Some OE turbos are - and oilcooled . Check for rust. If rust gets inside the turbo it can damage turbos internally.
-Any signs of overheating could spell turbo problems. White hair-line cracks on the exhaust manifold are a giveaway that the engine has been running hot.
-A leak down and compression test will alert you to sealing problems between the head and engine block.
-Even well cared for turbos may need replacing if they have enough miles on them. Try to buy the car after the previous ower spent the bucks on a new turbo.
