Just make sure you pop out the shaft seal and get a new one. Put on timing cover first to get it nice and sealed to the bottom u shaped gasket, then bolt in on in criss/cross pattern, and then tap the seal back in and on to the shaft. I tried it three times the other way and it kept leaking (shaft seal would roll and bind. 4th time, did it that way and worked like a charm! Hope that makes sense.
