I used a fine thread sheet rock screw, not course thread to further minimize the chance of scaring anything. Can't thank you enough for mentioning that bypass hose. Really appreciate you doing this vid. It helped me.

I have my 2000 Nissan Frontier 3.3L in the shop and would have not known about replacing the cam shaft seals and the hose - I was able to call them this morning and add those to the list - they were almost ready to close it back up. Many thanks... 🤓🤓

thanks for identifying the bypass hose! doing all this to my 04 frontier right now

I just took a small standard screw driver and tapped it in where the seal contacts the cam shaft to break that part away, then I was able to stick in a larger screwdriver and pop the seal right out. I tried drilling through first, but it was really difficult to drill into the inner metal ring of the seal while keeping the bit where I wanted it. After inspecting the new ones and seeing there was room to do this, it seems like the fastest and easiest way to go. The outer seat for the seal is aluminum, so if anyone tries this method it should ONLY be done where the seal contacts the cam (and crank) shafts. The shafts themselves are pretty dang hard, so if you do this carefully it shouldn't scratch those.

great tip on removing those seals I never seen it done that way. I will try that next time. I'm no mechanic but I think I would have replaced the tensioning pully with a new bearing or the entire thing if it comes that way. I take it this is a rotary engine? looks very much like my old porche 944 engine. that tensioner on my porche got loud over time.

Does the back plate come off when you take off the cam sprockets or are there more bolts around it?

Service notes say remove oil pump to do crank seal. Were you able to replace the seal without removing the oil pump?

Thanks for putting the time into making this video. I have a question, what did you use to take off the cam sprocket?? Im thinking of purchasing a special tool at the parts store. What is the torque specification for these sprockets?? Thanks again god bless have a good day.

Muy. Agradecido por los vídeos. Externa por ello epodido Aser mi propio carro porq no tenía para pagar por crisis dela pandemia grasias

Im surprised there isn't more comments. Thank you for posting this video. I'm about to do this job on my pathfinder. Its going to be my first time doing a timing belt. I understand how everything works and been doing all of my own mechanic work since before i was old enough to drive but this is a big one for me. I appreciate you posting this video. The reason im doing it is cause my crank seal is leaking. Did you have any problems getting the camshaft sprockets off? Did you use an impact?

Great video. Any tips on getting the crankshaft sprocket off? Mine seems to be wedged on pretty good. Thanks!

Nice video. I have a question. Did you line your timing up prior to taking your timing belt and cam shaft sprocket off?

When is the right time to take the cam pulleys off to replace the seals? I’m worried that if I take them off separately and they move it might throw off the timing. And then I’ll really be screwed.

A lot of bad videos not showing step by step how to align marks . They only show what is already done

Question, to replace the crank seal, how did you get the crank gear off?
