My Ford 7.3 Has a Hard Time pulling My 5th Wheel Up a Hill. What Can Be Done? The Ford 7.3 Diesel is Rated at 185 HP @ 2800RPM if what You Need is More Power. Turbo Charging is the way to go. Or See our TOW & GO Packages. See the Next Question first.
 

 

My 1990 Ford 7.3 has 120,000 mile on the engine. Is it safe to Turbo charge it now?

 

NO. Your engine already has excessive Blow-by Combustion gases in crankcase). This is routed through the crankcase depression regulator and vented into the intake manifold and burned in the Cylinder. This oil vapor will raise combustion temperatures to the point of detonating pistons. Remove your Air Filter housing and look for liquid oil in the bottom of the intake manifold. If it is more than a light sheen than your blow-by is to much. Here is a Picture of a Extremely Detonated Piston. We have a shop full of    these examples. Click on Piston

I've often heard that the 6.9 and the 7.3 have an affinity for blowing head Gaskets. Is this True? Every engine CAN have a head gasket problem. But I can tell you that we disassemble 5 to 10 of these engines a week and we may have found 1 or 2 in the last year that may have had a head gasket problem. The problem with the 7.3 is cavitation holes a appear in the cylinders on the drivers side of the engine. This is always mistaken for a head gasket problem.  This is a preventable problem but not a curable problem after it happens.
Why should I have all the roller lifters replaced when My engine is Redone? These roller lifters have small needle bearings in them . After a hundred thousand miles or so these bearings can become fatigued. The roller falls out and damages your camshaft and there goes the money you saved by not having new lifters installed.
Why should I buy a Running Complete engine instead of a short or long block? In the long run a running complete engine, with injector pump,injectors,glowplugs,intake,fuel pump and fuel system saves a lot of time in pre-installation. And Our Completes have been test run and complete with oil and filter.
