Is this d16 crankshaft ok to use in my NA build?
This crank is for my NA build, but I am posting this question in both the NA and FI forums because alot of knowledgable people frequent both places. I spun a rod bearing in my old motor, and the crankshaft isn't worth trying to save--so I had another d16 motor sitting aroung with about 175k on it. The journals of this (other) crank aren't in the best shape but they look acceptable to use in my build. My question is that on this crank that I want to use, there is a groove created by a dirty main-seal digging into the crank over time--I am afraid when I have it in the car with a new main seal on it, the rough groove will ruin the new main seal and create a leak. Its on the part where the flywheel bolts to and the main seal rides, I know the pics aren't the best but you can sort of make out the groove below. What do you guys think, is it ok to use, or will it ruin the main seal and create oil leaks? thanks in advance, Jay.

It's hard to see how deep the groove is in the pictures. I would probably just find another crank to avoid any leaks. The rear main seal is a PITA to replace if it goes out and you can find a D16 crank for pretty cheap. I picked one up for $25 when I was doing my build.

Thanks for the reply--Also I am building up a d16a6 motor (not-vtec) I know the journal sizes are the same on all d16 cranks, so I believe I can use a crank from any d16 (d16z6, d16y8) correct?

Any D16 crank should work and if I remember correctly, the A6 had better oiling holes.

Interesting. I've never seen those before. There's no price listed. It might be easier and cheaper just to replace the crank. Do you know how much the speedi sleeves go for?

Those Speedi-Sleeves are interesting!! Thanks guy, I have NEVER seen or heard of those before--I have seen some grooves in cranks that guys were building but they never made any mention of it, and I don't know how the builds turned out or if they leaked or not. I guess its a pretty common problem--This is why you should change your main seal at about 100k!!

I bet if I brought the crank to a good machine shop around here--they could probably measure, and install the SKF speedi-sleeve--what a great idea!! thanks again, Jay.

Since your building up your engine why not just get a micro polish done on the journals..

I just makes you feel all warm inside knowing that the oil is just gliding along..

The journals could use a micro polish--def. But its not the journals that have the problem--its the shoulder of the crank where the rear main-seal rides--the old seal dug a 3/8mm groove in shoulder of the crank (dirt must have got caught between the seal rubber and the steel crank surface) so the speedi sleeve or another crank seems like the best bet! thanks

The groove is supposed to be there? Who told you that? I hope your kidding--that groove is def. NOT supposed to be there ( I hope we are talking about the same thing)

We must be talking about something different.. I am talking about the bright shiny thing that is the thickness of a paperclip that is on the crank seal journal..

we are all talking about the same animal.
speedi sleeves are just pressed over the end when the grooves is too deap to be taken out.

Yes that is correct, the part you marked in red is where the groove is. Trust me though, there is NOT supposed to be a groove there!! It is from dirt getting under the crank seal and over many miles digging a little ditch from the rotations!! You are probably used to seeing used cranks--look at a brand new Honda crank in the package--I GUARANTEE there won't be any grooves in that area!!!

Hmm.. The strange thing is that its a perfect line around there.. And the B16 that I just finished rebuilding has that groove and doesnt leak a drop of oil..

Its a perfect line because if a piece of dirt gets caught under the lip of the seal--as the crank rotates (assuming the crank is dead straight) you will get a perfectly straight groove cut into the crank over time!! Thats the kind of input I am looking for--that you have the groove and doesn't leak any oil--you should check by your trans though, see if oil is dripping out of your engine/trans interface....I would like to put it in as is--but I don't want leaks down the road--and I especially don't want to ruin a perfectly good seal....

Re: Is this d16 crankshaft ok to use in my NA build? (d16dcoe45)
I had the engine in for about 500 miles and pulled it out to install into another car.. I changed the clutch and tranny and I didnt see any oil leaking from it at all..
