V4

[ultrafast]

Anybody got a pic or advice on cutting the exhaust cavity for a V4 crossflow looks pretty restrictive to me

Scribed--- Gettin ready to "upgrade" my 140 also. Gary

If you are working on an early crossflow, up through 77, you can remove the rib in the exhaust chest, such as was done to this 135. Makes it similar to the 78 140 blocks.

EMDSAPMGR---- Am I correct then thinkin that my 84 140 block should be good? Thanks Gary

Anybody cut the bridge out shouldn't be hard to bypass it

No don't do that. You must be crazy ...

Hey would ya bleve I put this sob back together today and the cser still leaks? Mother effer ...!

Thinkin it's from that 'thin' area next to the water diverter? Piss me off ...

It'll already have the cut out.

Dont cut any lower . You'll hit water. Then you'll get to weld it up. Trust me.

Pehaps you could elaborate on the "water leak." Does it leak at the bottom of the head-down onto the lower cowing, or is in an internal leak that's getting water into that lower cyl? Different fixes.

Don't wanna hijack Don's thread ... but ... It's leaking externally. Dago fly cut the heads last week so they should be okay. ~125 psi on all 4 now. Tiny leak from the stb head's gone but port's still leaking a good drip. As advised I even used RTV on the water jacket this time?

If'n I gotta tear this thing down again'n mill the block I'm gonna have a friggin conniption fit. I mean I'll do it if I have to, but I'm still gonna have a friggin conniption.

Dumb question but should I not be runnin a hose straight to the water tube?

Hey Don I got yer filler blocks down at the shop so whenever ya wanna swing by. Lemme know if you need anything else.

Tape off the bores and put a bit of metal marine tex or jb stick on the spot. Then deck it with a large file. Use rtv and a new gasket, tighten bolts hand tight then let the RTV set up a bit then torque it. Should get you by for a while.

[71V153]

Well we're gonna try again tomorrow. Got another head gasket.

Gonna try'n bridge that gap with sumpthin. Ain't decided what just yet. Too bad ya cain't fill it with bullchit, cuz I got plenty of that ...

Went ahead'n stuck the lower on. (No fugly motor jokes please ...) Figger it'd be less pressure against the water jacket runnin on muffs?

Have my doubts, but we'll see. If it leaks this time it's gonna leak til it corrodes shut ...

Hey It looks great! I like the marine tex repair--- has worked for me! Relax You will find the problem- It's most likely something weird. I use the new Universel Blue gasket dressing--- Permatex also makes it. Gary

I'm a big fan of JB weld myself, but same difference. Ya I know it works miracles. Hoping it can mend my broken balls over this project ... But I digress

JB Weld doesnt belong in the same book as marine tex. Marine Tex is a hands down superior product.
