Just wondering how many guys broke oil pickups this year? I broke 2...lost 1 motor(spun 2 rods) and caught the next one because I installed a BIG red oil light after the first.

I broke 1 in a wreck. but always have to watch them for cracks. I have found cracks in them for no reason i know of.

We pull our pan every 3 or 4 races and check pick up and bearings.

I broke 2 in '04, the last one cost me a crank and main bearings. These were the cheap gold ones from China and they broke where the tube joins the screen. I won't run them any more. Get a Kevko or other name brand.

These were supposed to be from champ pans. Balance job is second to none but the track was extremely rough. The bolt tab was broken and the tube brokes at the bend area. Just trying to see if I had the only bad luck with pickups. Anyone try those bolt on bottom pickups where the oil ***** straight up? You can get them at Speedway motors.

I snapped an oil pump right in the bend where it bolts to the block. Oil pressure dropped to 0 and I killed it. Pulled the oil pan the next day and found about 85% of the pump in the oil pan and the other 15% still bolted to the motor.

I always freeze the pickup and bol the pump bottom in water then put it into the pump base with locktite for sleeves. Use only a small amount and be careful with it. It slides in pretty easy just remember to use gloves. I use the pickups with the brackets that bolt to the pump. I (knock on wood) have not lost one yet. I have seen some broken ones but they were from where the person who put them in beat them in with a hammer and they cracked where the little dents were. I have also seen a failure when using one of the pump pickup drivers some of the companies sell. The guy drove it in to hard and smashed the beaded area that seats against the pump and it cracked.

I broke on on the pan comp products is selling for 135. The pan held oil good as far as control the psi, but the pickup broke one night. The track was a little rutted up, It broke the welded support(had a support branch off of it to bolt to the pump), it broke off and fell into the pan. Luckly it was at low rpm, not at high. Nothing was damaged.
I have welded them on, and like the idea of freezing it and using loctite, make sure to lick the picup to check the temp while doing it.
Whatever you have try something, weather welding/brazing loctiting, something it almost cost me a TON of money.

You know you're going to feel really bad when you get on here and see a topic that says "Need help with oil pump pickup frozen to tongue"

I like ego's idea except for the boiling part. Why not got to local weld supply store a buy a 250 degree temple stick and then use that while you heat the bore of the pick up hole on the pump with a torch. Anything that pumps oil should not be boiled.

let me guess your running a m55 style pump if you are you will continue to break them until you change to a 5bolt pump.

We almost always run the M55 pump. The reason to boil it is so you do not over heat one area and crack the housing, also boiling will not cause a problem with the pressure spring.
ZERO- you only need to check the temp with your toung when the part frosts over when you pull it from the freezer.

You won't crack the huosing with a propane torch heating it the housing to 250 degrees. 212 degrees is what your heating the housing to now. If you do things sensibly you can accomplish wonders. My concern was water damage to the pump. Any way the point was not too argue. I have been sweat fitting interfernce fits for 20 years and I never use boiling water, liquid nitrogen, dry ice, freezer, oxy acetylene, induction heaters, propane, heating elements, and yes sometimes the BIG hammer. But hey what do I know?

I agree 100% with you. Where the problem lies is with someone without your knowledge base with the tourch. They could cook the pressure spring or crack the housing. I do not boil the whole pump, just the bottom plate. It is just easier for me to do it this way because I can be doing other things while it is warming up. I have 2 pickups in the freezer in my shop right now and do not have an engine to build. When I get ready just warm the pump base and slide it right in.
For someone who had not done it alot the boiling water has less of a chance to get them into trouble.

Most of the pickups I have seen are not bent correctly to align the tab hole to the pump. If this is the case I would heat the tube and bend it to align the bolt hole and take the pressure off the tab.
