I recently bought a 2001 mp3 with 155k
Had a bad trans ,replaced it with a used one ,Smoked bad ,So I checked compression and it was 120 on two on left and 130 on two right,I put in all new valve guide seals /Didn't help ,Two valves were bad ,So I took head off ,I had one from my 2003 Mazda speed ,Found out that also had two bent valves ,Took the two valves from other head ,lapped them and installed in head ,Put it all back together with new head gasket and bolts ,Thing still smokes 5 -10 min ,Does fine after that ,I try ed 15w40 didn't help burns a quart a day ,So do you think it needs rings or just valve guide seals or both ? Anybody just want to buy it for $1500 or trade me a escort or focus or festiva or something
