Oil pump failure (*Pic)
1 Attachment(s)
Stock gears + Motor was spun to 8k on ocassion (not tach indicated 8k but mspnp 8k).
Attachment 198465 Failure occured around stock revlimit though. I remember Joe saying he wanted to see my pump when my motor ate it and until the other day I totally forgot to pull it apart, I think my welder buddy can fix it though :laugh: -Dean |
Trust me, I know the feeling...
That sucks big time man, that block is gone as it is going to cost more to bring that block to specs than simply just getting a used one from a JY and call it a day. You should take pics of the oil residue in the pan, I bet you can take some cool shrapnel photos. Mine happened a week ago, stock ECU, revved to 7,000 (I even have a shift light and oil mechanical gauge), boostin to 15 psi, religiously change the oil every 2 to 3,000 miles BUT I had a lightened aftermarket crank pulley (no harmonic balancer). Did you had stock harmonic or aftermarket? |
I could use this for advertising, nudge nudge. Sorry to hear about your loss. I hope your rebuild goes well.
|
Yikes! I think I am pulling the motor. Travis, you will be hearing from me.
|
Glad I picked up a billet gear set for my build.

And there is no rebuild, FE3 is going in instead |
I'll be ordering me some soon as well
|
Glad I got the BE OP. I'm going to spin the piss out of this thing.
|
Ouch! Sorry to hear about it letting go man... At least you have a gameplan already in place though.
|
So wait.. what exactly caused it to fail? Spinning it too high.. or the power?
|
Based on his sig, it has some power and loves trannies... I'm not big on trannies, but to each their own.

http://www.boundaryengineering.com/hfoil.php Our billet gears are chrome-moly which hold together under extreme conditions, a true high performance upgrade with peace of mind. |
Is it possible than instead of ordering the gears, checking for clearances and if not I must return the gears for better spec one, than to just send the OEM oil pump and the gears are sent with those pump clearances...?

Check out our info on oil pumps and gears. That should help explain what happened.

Stuard D, Are you going to answer the question?
I think it makes a lot of sense instead of chasing around back and forth on the mail which is the correct gearing clearance. As I have read others receive the gears and is not the correct one for the housing and has to be sent back. It is even better that is the shop who checks for clearances. I bet your measurements on the pump would be more accurate than the ones I will perform. |

Mazpr, I will try and answer the question but I am not sure what you are asking.
Of all the gear sets we have shipped less than 2% have been returned for clearance issues. Two returns stand out, one the customer received a gear set that the inner gear thickness was borderline max yet the outer was in spec. Another return was due to an out of spec tooth clearance. I think there was one more set that was returned because the side clearance was over the high limit for his housing. We have recently created a process where each gear set is hand fitted and checked to a stock housing. The customer receives a listing of the clearances that is signed and dated. If the gear set is out of spec in the customer's housing, then the housing is worn too much and needs to be replaced. If you would like to send in your (clean) housing for fitment, that would be fine. You will receive a listing of the clearances that is signed and dated. Turn around time is 2-4 days after receipt of the housing. Please provide name, address, phone and email. Ship to: Boundary Engineering Machining Division 7 Dunham Drive New Fairfield, CT 06812 I hope I answered your questions. Stuart |
Stock or aftermarket balancer?

I did use an aftermarket lightened crank pulley which I used for more than 4 years when it was NA, but I guess the vibrations were to much for forced induction at 15 psi. ______________________ Stuart D, Thanks for the answer, that sounds great. |
