Very nice trick! I wanted to add that it's important to check the shaft-surface for scoring due to wear from the old seal-lip onto it. It's particularly important when reinstalling the new seal, that the new seal's lip doesn't correspond with the old seal's lip mark/scoring if scoring is present. Otherwise you end up with the same leak as before and you have to do the job a second time... Hope this is helpful
Is that really a thing? I have never seen any oil seals leak before, and all the engines I've seen have a tiny bit of wear on their camshaft and crankshaft surfaces. As long as it's not rusted, or dented, a small amount of nearly invisible grooving seems perfectly normal, and the new seal should be flexible enough to seal up tight? The seal also doesn't need to be airtight, because the job of the PCV valve is to create a CONSTANT vacuum in the crankcase, so that the seals are always "sucking" air into them, rather than pushing oil out. If you remove your PCV valve like many shade tree mechanics do, then you'll end up having oil leaks, no matter how good your seals are, because at high RPM the crankcase can end up having a lot of pressure. The oil seals don't do well with pressure. Note, at WOT wide open throttle, the PCV valve opens up more in order to accommodate the drop in intake manifold vacuum, by increasing it's internal flow rating. At high vacuum during light cruise, the valve closes automatically to maintain a moderate vacuum in the crankcase. On a turbo vehicle, the PCV gets its vacuum from the air intake, pre-turbo, but STILL creates crankcase vacuum under boost.
Really work well for transmission oil seals where there is no gap between shaft and seal; the seal covers all outside the shaft. Bent-nail trick will work well
Very good to know, im trying to take the seal off my John Deere 70 PTO shaft, so I don't have to worry about the shaft, but im still struggling to get it out with a chisel. I'll try the nail method and see if it comes free.
a person takes responcibility! NOT ENOUGH of you! good video plastic screw driver break the structure that provides the tension to the case it will also make it easier! i was a race mechanic we rebuilt an engine in two hours between heats.... standard engine with hypo parts including a full race cam, it is really not that hard to rebuild a motor. the only time you need to split the cases is for rod and cam work.
Very informative and neat presentation! Hopefully, a tutorial on the carb cleaning and tune up will be uploaded soon? Anyway, keep up the good quality tutorials. 👍🏻
Thank you very much sir! As of now, I have a lineup of videos to upload in order to release some storage. By that time, I will be able to upload it soon. Thank you once again. Take care and God bless.
Another method, drill a small hole that way you can control where it goes, instead of potentially having the screw hit the camshaft. Drill the hole with a 1/16" bit, going slowly, keep wiping the oil off, because the seal backing is made out of stainless steel and if you go too fast it will ruin your drillbit. You have to wipe the oil off the bit, if it has too much grease or oil it won't drill a hole.
Unfortunately, oil seals are designed to be used only once. You cannot remove them without breaking it. I guess you can try to push it from the inside if it is accessible. If that is possible, then you can remove it without damaging it, but it can be quite difficult to do.
Actually this is only a spare engine head. I just kept it at home for future use. It doesn't have rocker cover because it is mainly used in the vehicle.
I tried to search for it and this is what I've found. 91213-PD2-004 (Arai) 91213-PE1-721 (NOK) These two are different brands but applies the same spec for a non VTEC engine, specifically D12B, D13B and D15B non VTEC. Please have it check at your nearest dealership and auto supply store for much more assurance and availability of the part.
remember if you nick seal walls or shaft your engine is done at that level of work! most seals are only big enough to hold the pressure of the fluid there is no excess coverage!
Hi sir. Thank you very much for watching my video. I will take note of it and upload a video about it in the future. Thank you once again. Keep safe sir.
