Title: Intek 40 vertical to horizontal conversion
Post by: BeasTHEast on March 28, 2014, 04:56:08 pm
Ok, so iv got a Intek 40 sitting around collecting dust and have been thinking of doing a vertical to horizontal conversion to it, I can solve all the problems except the oiling issue. Seeing as how its full pressure lube can I just route the pumps pickup to were the oil will be settled? Iv thought about putting some type of reservoir were the dipstick connects to the block so that it can hold the right amount of oil and not to much in the engine so the crank weights clear the oil level. I'm no engineer so I would love it if someone could point out the reasons why this setup wont work im sure someone has thought about doing it.

they don't make a horizontal intek that im aware of but if you are saying to make a vert intek into a horizontal oil is not the only prob you also have the carb to deal with

Hahah yea that's a typo but yea it would need a intake to fit the carb in the right position and don't forget it would need some sort of engine mount to hold it down... but what do you think of how the oiling system and how it should be modified?

Why not just get a vanny horizontal ?

Because I can find these inteks for low prices the one i have now was bought for 60 bucks and came with a mower attached to it lol also were can i find a valve keeper dropped one in the grass :/

Get billet valve retainers.   You will need them. 

As for the oiling I'd be worried about the pump drawing oil that far.  They aren't designed to pull oil, they are deigned to be submerged in oil.   I'd bypass the stock pump and use an electric oil pump.   Benefit of that is you can run oil squirters on the pistons.

Im wanting to use the ec valve setup just didnt know if it came with keepers, i was kinda shooting for a simi dry sump but if you can point me in the direction of an electric pump cheaper than a ragb i would try it that way. Do you think the pump could be mounted internally? Iv been reading on dry sump setups in the newer V Twins and they always mention the need for two pumps one of them needs to scavange or pull the oil out. Would i need to scavange if im using the origanal pickups? Thanks for your help im sure to get a lot if great ideas on this forum!

Order new valves.   You will need them if your running the dual springs.   They will come with new keepers.

As for the pump I know there are guys that are running external electric oil pumps.   Do a search on here, there is a thread that talks about it.   I wouldn't worry about a dry sump setup.   It will hold enough oil and not hit the crank.

Iv been looking at some pretty afordable pumps but have no clue as to what the spec it needs to be
All i found here was that they used cheap pumps
I found a link to a fuel pump on here but its only rated to 8 psi

What are you going to use the motor for when converted?

I wish the pump could handle an extra 6" of line but it would also pump aginst gravity right, this is to much strain?

What are you going to use the motor for when converted?
Dont really know yet i just need some projects would also like to have the only horizontal  intek twin :D

A vertical Intek built runs good..why change it?  Run it as is...there are no problems to have to re engineer.

Ok I know that this engine is fine the way it is it runs smooth and great. Im not doing this to fix an issue or for performance and im not reinventing the wheel just have an old intek i want to change up, do somthing different with it. Ive got the time for it so why not. I also think its more cosmeticly appealing. Also if i can even pull it off the engine could be used in a variety of different setups.

If I was you I would try ask tank about this subject he's really big inteks and knows a lot about them

I tried this very same idea. I made a pick up for the stock oil pump and tested it on the bench with a custom tool to turn the oil pump with a drill to see if the stock pump could pull the oil out of the bottom of the block. The issues i ran into was the oil drained out of the system when the motor was turned off. Also I realized no oil was getting to the rockers or valves. As for the carb issue i had an E.C. carb adapter and used that to rotate the carb 90 degrees. I also made a custom engine stand to hold the motor using the stock mounting pattern. I ran the motor for about a min and nothing blew up but I shut it off because no oil was getting to the valves.

Good to hear, I have been trying to find a good but cheap pump for it, been very busy trying to set aside some money for the project?. So the pump couldn't get it to the valves what size tube are you using to feed the pump? Get any pressure measurements?

The valves are splash lube even in the verticle setup. Its takes rpm to get it there. and a closed system meaning everything in olace like valve covers. Vannys are the same way and they lube the rockers no problem. SO rockers arent your worries the the obsticle your gonna have to figure out is the drain back after shutting off. Disect a horizontal vanny pump and pick up you will learn alot.

George summed it up. The main issue is stopping the drain back.

Some type of Check valve of some sort upon pickup entry could work.
