Built an LS VTEC for my 96 Teg.

Unsure of how to hook it up, I ran a line from the valve cover directly to the top of the breather box. On the first start, everything was good. While checking everything over oil began pouring out from the lower side of the timing case.

After removing the cover, re-installing the crank pulley and running it again, we saw the oil coming from the oil pump crank seal. It was only a fluke that I went to pull the dipstick and see how much I had lost and it blew the stick out of the engine like a nerf dart. Realized the crank case was being pressurized and I immediately knew what I had done wrong. Silly mistake, research is your friend. I was fuzzy on how to hook it up, made a guess. My bad.

Cleaned everything off with brake cleaner, ran it again. No leaks. Then I pulled the horse shoe out of my *** and wrote a post on HT.

No bashing allowed, I know I made a mistake.

 

damn hope you didnt mess up your motor

 

I'm hoping too...

 

This is good info so others don't make the same mistake, did you have to redo the oil pump seal??

 

No I didn't have to redo it, but I'm keeping a close eye on it, looking for even the smallest amount of oil. I'll replace it if I see any. I wouldn't have known any better if I hadn't checked the oil either, just a fluke that I did. My next step was to remove the oil pump, with the engine still in the car to inspect it, thinking that the pump or the seal was to blame. Damn.

 

Thanks for giving everyone a heads up! Its much easier to learn from others' mistakes. :-)

 

If you got oil on your timing belt then it's a good idea to replace it.

Also how did you change it to make it work correctly? Let us know the proper way to attach everything so those of us building LS/VTEC's will know.

*edit I found this pic in this thread, is this how you hooked it up? https://honda-tech.com/forums/all-motor-naturally-aspirated-44/how-build-%22reliable%22-lsvtec-b20vtec-1676914/



There is a hose from the breather box to the block. The PCV valve goes in the other hold in the breather box, with a tube to the intake manifold. Then there should be a tube from the valve cover to the air intake pipe.

 

The black nipple without a hose on the breather box should go to a hose connected to the PCV valve. The hose coming out of the PCV valve should go to your intake manifold. The nipples coming out of your valve cover should run to a hose running to your intake.

This is if you are running a stock PCV system not if you are running a catch can pcv system.

 

No I ran a hose from the nipple on the right to the tap on the top of the valve cover. I know, I'm cringing too. It just looped itself and pressurized everything. Scary.

I learned my lesson. Right now it's unplugged and I'm running an open tap on the valve cover. I'm using ITB's so it's not as easy to hook everything up as it should be from the factory.
