Turbo install valley pan drain holes/firewall questions

[saburai]

Hi Gang!
I've just about got all my parts together for the ATS turbo installation on my '90 7.3 E4od F-250. Upgraded turbo and and the balance of the kit is coming from typ4 Russ, he's been great to deal with even though he's super busy with work problems. Thanks Russ! I've got the Banks down pipe and a cat back Diamond Eye exhaust system waiting to go on as well as boost and pyrometer gauges and some 3/4" aluminized sleeving for cables and vacuum lines. I'm super pyched about the whole thing! Couple of questions, I looked around but I couldn't find any pictures. Does anyone have any pics of the valley pan holes that I have to poke? I'm assuming that I just poke around few 1/8-1/4" holes in the pans though the same hole that the CDR grommet is in... Next, you all posted some pictures of the clearancing necessary to fit the down pipe. I don't have access to a Porta power, so do I just use a 2" pipe or a 2x4? I'm assuming that I come in from the top and pry upward against the firewall levering off of the bellhousing area. Is that about right? Any other tips or anything else I'm missing? After I finish the installation, it's a road trip to Dieselcrawler's place to check the timing and finish up the exhaust system and soak up some expert advice.
Thanks All!

Having re&re'd a couple turbos on IDIs, a downpipe on a PSD, and a couple clutch jobs..... I would seriously look at a 2" body lift if I still owned one of these trucks.

A body lift makes it easy but you have plenty of room if you just replace the body bushings, they tend to get squashed down over time

Four of them right? Is it a hard job?

Thanks! Have you done this? I'm wondering how long it takes to do and if the hockey puck mod would work with the stock bolts...

All I ever did was use a punch tip on an air hammer. I would just make one hole straight down in the middle of the grommet. I'd guess that it would be about 3/8" in diameter. I never had any problems. I wouldn't use a drill. There would be WAY too many shavings falling down inside the engine.

Thanks gents! Any input on the firewall massage technique? New cab mounts with a small spacer sounds good but I don't think I've got the time to get into that at the moment.

BFH! That's all I have used. If the pinch weld gives you trouble, I've used the chisel on my air hammer to make a couple of cuts in it. It bends easy after you talk to it right.

You're doing this with the engine in? How the #$@¥ do you have room to swing the hammer?

A couple relief cuts and a ricer scissor jack on the bell housing is how I did my massaging.

Did you use a Sawzall from the front to do the cuts?

 

[pafixitman]

Yep.

Maybe I didn't use the hammer with the engine in. I can't really remember any more to be honest. I haven't done this since at least 2001 and will do it to mine before the engine goes back in.

I feel like I got my DP in without messing with the firewall? I think I fought it a bit though. I could be wrong, and maybe justbhave forgoten about my firewall abuse.

I never did anything with my turbo drain on my truck, I wonder if this hurt anything.
