Valvecover breather
on: Tue 19 of Jun, 2018 [12:11 UTC] score: 0.00
Hello,
I am in The process of changing the original valve covers out for some aftermarket units .
There is a PCV valve on the lifter valley pan .
Is it mandatory for the valve covers to have their own individual breathers ?
Can there be one just one on one side, or is one for each valve cover required ?
Thanks

Oldboy,

You'll be good to go with that setup. as long as there's a place to fill it with oil and a way for air to get into the engine, you're good. Be sure to replace the PCV. they only cost a few bucks. Cheap insurance!

> Hello,
Okay there is a pcv on lifter valley cover, also the oil fill cover, screw in type, non vented.
I am going to put one breather on the passenger side valve cover, mounted a good distance from the pcv valve.
This will be the only venting on the motor.

I currently gave an airtight crankcase oil fill plug. A Hothead unit that screws into the lifter valley pan.
The new reproduction valve covers do you not have a provision for breathers . I can drill and modify reuse one of the aftermarket breathers off the old valve covers .
So if I only use one valve cover with a breather and I have a PCV valve all is good?
Thanks.

Do you still have the oil filler tube in place on your engine? If so, are you using a "breather-type" filler cap? If you still have a vented cap on your filler tube, you have everything you need and breathers on the valve/rocker covers aren't necessary for the system to work.

All it takes is a way to move fresh air into the crankcase to replace the fumes that are drawn out through the valley-mounted PCV.

If you wanted to take the route of eliminating the filler tube or capping it with an airtight cap , then by all means add a breather to either or both valve/rocker covers. Whatever you do, you still need a way to add oil though.

Some think cover mounted breathers look cool... others like a clean look. Either way is acceptable depending on what you do with the filler tube.

Good luck!

Dave

No, you can use the OEM oil fill cap, it's vented for air flow. If you must cause damage to the covers, I'd think one on each side as far away from the PCV valve would be best.

392 cam

Do I need any head work done on my 300d, 392 heads to run a Howards flat tappet, hydraulic cam with a .471 valve lift? I just had the heads done and set up for the stock cam, including springs.
I am assuming I will need to replace the springs???
Thanks,
Jon

Jon: Hot Heads spring no. 40062.110 @ $119.95 will fix you up on springs. You will also need positive intake seals #40080 @ $19.95. Do not put seals on the hemi exhaust. Have fun, Bob

You may have to cut down (shorten) your valve guides for retainer clearance.

You may need longer valve stems to allow for more spring travel to avoid coil bind . Howards tech number

NOS Chrysler Pistions
on: Fri 01 of Jun, 2018 [00:17 UTC] score: 0.00
Back many years ago (1959-1965) I worked at a local Mopar dealer by the name of Goodwin Dodge. The manager for the parts department was cleaning out the storage area. There were 8 boxes of Chrysler pistons some were for 6 cylinders some for poly motors and some for hemi's. being the packrat I am I gladly and proudly took them. I ended putting them in the garage and I never used them in a single project. well here it is 50-55 years later and I'm sick of them sitting their collecting dust. I would love to sell them but their is one major problem I have no clue what any of them fit! I'm hoping that one of you guys could help me Identify them. They are sold by a company called repco out of warren Michigan I have the part numbers available if that is any help. please get in touch with me if you know ANY information about these pistons and of course if you would like to purchase any also tell me. for the right price they can be yours

Repco appears to be an Australian company .Still in business but offering Chrysler pistons back to 2005 . If you google it it will come up . Doubt they have much info on your pistons. It still exists.

11/32 Valves for hemis
on: Thu 31 of May, 2018 [22:22 UTC] score: 0.00
Doing a build on a 330 DeSoto. This is getting a blower, EFI, radical roller cam, etc. Looking at using racing type valves. Anybody have any experience using sbc valves that are tuliped or angle cut? Would love to hear from anyone that has flowbenched them in a Hemi. I realize the chamber shape may impact how well these tricks improve (or don’t) the flow.

392 Lifters
on: Wed 30 of May, 2018 [14:32 UTC] score: 0.00
I noticed I have a lifter that comes and goes while my car is idling. What would cause this and is there a remedy without tearing into the engine. The motor holds 50lbs of oil pressure at idle.

If you don't have adj valve train you might try Casite Engine Honey or STP & see if it helps, or go the other way and add some ATF or MMO. If one is bad get a lifter for the early 361-413, number is usually 812, though one manufacturer uses that number for s. b. chevy.

276 Desoto to BW R-10
on: Sat 26 of May, 2018 [20:02 UTC] score: 0.00
New poster here....have a 50 Plymouth project car with a very tired flathead 6 and a later model 52 Plymouth 3 speed manual with Borg Warner overdrive. Tranny is in great condition, and I love the OD. Buddy of mine has a rebuilt 276 Desoto Hemi (stock 160 HP) that I'm awfully tempted to swap in, but not sure about the compatibility with the BW OD tranny. Seems to be conflicting info out there as to whether it will mate up or not. Does anyone have info on bellhousing or other compatibility issues? I think the tranny itself will stand up to the hp and torque of the hemi...just want a cruiser, not a racer...no speed shifting that column shift!

Thanks for the detailed info....the 276 has the bellhousing with it, so that's a start.
