BlueBullet620 Posted July 16, 2021 Report Share Posted July 16, 2021 1974 620 with a 91 KA24de out of a 240sx. I was resealing the oil pan and I steered a bolt off that goes into the oil pump. I tried to solve this problem but I completely screwed the pooch. Did some research and I'm decided since I do not know mileage on the motor, the best thing to do is, timing chain, water pump and oil pump, and valve cover gasket all at the same time. Which is everything on the outside of the motor besides the Starter and alternator. The only question I have at this point is, what is a quality timing chain kit and oil pump. OEM is possible for the timing chain kit but I'm very worried about buying a low quality oil pump. And OEM oil pumps seem to be sold out. Furthermore Amazon has a laundry list of them but I dont trust any amazon seller . At all. Quote Link to comment
Bleach Posted July 16, 2021 Report Share Posted July 16, 2021 What brands are available on Rockauto.com ? Are any of those what you consider to be a quality part? Quote Link to comment

banzai510(hainz) Posted July 16, 2021 Report Share Posted July 16, 2021 get a Hitachi oil pump!!!!!!!!!!!! its its 25 $ then its Chinese. Get a Hitachi oil pump around 60-70$ used to be 100$ but think they trying to get rid of them. Get made in Japan units is best. Not all rockauto is great. Look for place of orgin Quote Link to comment
datzenmike Posted July 16, 2021 Report Share Posted July 16, 2021 The oil pump on the S13 KA24DE is behind the front of the timing chain cover and internally driven off the crank. Nothing on the oil pan bolts into it. Quote Link to comment
BlueBullet620 Posted July 16, 2021 Author Report Share Posted July 16, 2021 Mike, your right the oil pan bolts into the lower timing cover which the oil pan bolts to. And the oil pan and sandwiched in between. My oil pressure is fine but as I don't know the mileage or age of anything on the motor I might as well if I'm taking the cover off. Quote Link to comment
datzenmike Posted July 16, 2021 Report Share Posted July 16, 2021 The oil pan bolts won't go into the oil pump. If one is sheared off the ones on either side will seal the oil pan gasket. 23 minutes ago, BlueBullet620 said: My oil pressure is fine but as I don't know the mileage or age of anything on the motor I might as well if I'm taking the cover off. Everything on the engine is unknown but it isn't getting replaced. Quote Link to comment
BlueBullet620 Posted July 16, 2021 Author Report Share Posted July 16, 2021 With the sheered bolt , I tried to tap a new one and tremendously fucked it up. The hoke I drilled and tapped is very crooked. Inexperience mixed with trying to "just get it done" . I'm replacing everything I can short of the breaking open the block. Relatively cheap insurance and fits my budget. It's not going to be a race truck or anything special. Just something I can reliably drive hard at stock power levels. Quote Link to comment
datzenmike Posted July 16, 2021 Report Share Posted July 16, 2021 You're replacing the entire timing cover? JB weld the hole up and do again. Or just seal it with RTV and skip that bolt. The bolt couldn't have gone into thew oil. pump. Quote Link to comment
BlueBullet620 Posted July 17, 2021 Author Report Share Posted July 17, 2021 The issue was that it was leaking from the oil pan before I screwed everything up. So I want the motor to be in better condition than when I started. I dont want to skip a bolt. As it putting a weak point in the system. While JB weld could work I want to do it "right". 1 Quote Link to comment
Stoffregen Motorsports Posted July 17, 2021 Report Share Posted July 17, 2021 You could always slightly oversize the bolt. if it's a 6mm bolt, a 1/4-28 tap will make new threads in the stripped out hole. 1 Quote Link to comment
