Heads

TXlineman83 · Apr 23, 2014

Been waiting on the machine shop to magnaflux, square up, clean, install springs and put some bronze valve guides in my heads. Seems the guides are what's going to keep them in there longer. I personally firmly believe in them and thus have chosen not to rush the situation. However, the anticipation is killing me and wanted to gather the thoughts of everyone else on whether bronze valve guided were worth having done or not. Opinions roll. Tell me what u think.

I wouldn't do them on a 6.4. They don't have enough top end lubrication and will fail...

Really. I thought the idea of bronze guides was one their ability not to scar up and two they help to stabilize the valve train

So am I shooting myself in the foot. Do I Need to call the shop in the morning to cancel that and hope it's not too late

U are correct, but will happen if there is not proper lubrication on those on liners at higher rpm....they will generate excess heat and eventually fail.

I didn't personally, no cracks, .040" and so far so good?

So are the pushrods not like ones in say a SBC. Oil flow through them to the rocker arm providing lubrication I'm just trying to understand my motor a little better here.

Yea everyone has always said absolutely do not do bronze valve guides in these trucks

Hardened seats, decked, fluxed, springs of choice and done. Mine were cracked and shot, had to start with a new set..

I sure wish someone had warned me of that in my build thread. I sure hope it's not too late. I sent my shop an email and will have to call them as soon as I can. But heads have been in the shop since Monday.

i wouldnt do them. the top end lubrication is poor at best on these trucks, that is why you see people replacing rockers often, the ends wear out.

I was joking about the shop hating me. I don't care if they do or not. This is my build. Well really it's PSA's build bc I've learned most everything from here. Lol. I'm the customer. Do as I want. Lol. However, they do have my truck. My baby. My 3 kid in a sense. I want it treated right. Lol

Well, I had bronze guides installed in mine. Seems like a no-brainer to me but that's just my thoughts. I don't have any time on the engine (I seriously JUST fired it up last night). I replaced all the valve train components as preventative maintenance. Rockers, pushrods, lifters. My engine had 260,000km on it and the rockers looked like new. Very little wear on the contact areas.
this was my first diesel build, but I am satisfied I made the right decision. time will tell I suppose

I see in your signature your running APR studs. Are those new? I myself went with trusty ole ARPs.. So far, so good.

I wouldn't recommend bronze unless you can 'deal' with some hazing at idle (bronze guides shouldn't be run with valve stem seals)...so during off-boost conditions, they will pull in some oil...and it'll go out the tailpipe.

we don't run/recommend bronze guides for street trucks...most folks do not like the hazing on a new engine.

race truck/competition truck...different mindset of what's acceptable.
