That is a great line right there. 100% truth.

Crank up the pump.......

Need a clutch......

 

injectors=turbo and lift pump

turbo=head studs

govenor springs=valve springs

i could keep going

 

All of the above, new rods.

 

Bigger tires=New leaf springs
Bigger tires with above upgrades=New TC

 

Its all true,for sure but imho valve clearances are pretty much routine maintenace in everything I own almost, I'd say that I check my valves more than my oil sometimes...one of the best ways to stay on your top end!
also:
new car hauler = new water pump & rad

 

I should check mine but it's pretty quiet and starts good. I know the dozer has a 4BT and it's pretty bad. When I get home this winter I think I am going to lash them for dad before I leave again. It ticks pretty bad.

 

if the 4bt had a piston lift pump in it, that will tick pretty good. mine does anyway.

 

I have a 93 dodge, I was planning to get my valves adjusted, but with all of the other modifications I am going to( turbo, pump turned up, timing bump) do, I was needing to know if it would just be a better choice to get stronger springs. some questions I have- WHAT IS THE SAFE LINE TO DRAW ON THE BOOST PRESSURES THE SPRINGS CAN TAKE?
I am pushing over 30 lbs

 

30 lbs with these modifications( turbo, pump turned up, timing bump)

 

i wouldnt worry about boost. unless youre running an exhaust break or plan on running over 3500 rpm a lot thats when you think about springs. i just got done changing my valve springs about an hour ago. it was quite easy. you do need a few tools like a 1/2" torque wrench and a valve spring compressor.

 

From what I understand heavier springs are only needed if you plan on using an exhaust brake or revving the engine to 4000+rpm. Though, if you have the money and time it wouldn't hurt to do, and you have confidence later on if you plan on really pushing .

 

The second time this week someone beat me to the answer

 

Yeah my stock valve springs seemed to be ok, i run my truck up near 3600-3700 rpm. I dont know how long they would last up there though. Its pushing it.

Oh yeah- I did all 12 springs for about 200 bucks and thats with the Cummins brand springs, a spring compressor and a magnet!

 

A quart of Lucas in the oil quiets it some. The machine has about 10,000 hours on it. We've changed injector o-rings, manifold gaskets, and motor mounts in the last 15 years. I can't remember when we got it but shortly after that the cam broke, so that's the last time it was really opened up.

 

Valves float due to a combination of boost and rpm.
Mine started to float after repeated runs down the track running 38 psi and 3500-3700 rpm IIRC.

I changed all 12 to 60# and have run to 4100 rpm pushing 45 psi or so with no problems.
