Engine

[Joethafarmer]

I have a 1999 ford ranger and the head gasket was blown, so I took everything apart only to find out my intake was cracked, at this point I can get a new engine for 450 and should I replace the oil pump too because the truck has just over 200,000 miles on it? Also any tips would help me greatly because I'm only 18 and I've never taken apart an engine before

If you are or have pulled out the engine then yes, replace oil pump and oil pan gasket, also rear main seal(it is cheap, $8) but hard to get at in the vehicle.

If engine will not be removed, then no need to replace oil pump, but I would put in new rear main seal next time transmission is out.

A new engine for $450 would be a heck of a deal, a used engine for $450 could be buying someone else's problem, it is a gamble, even if warrantied.

Used intake and new head gaskets shouldn't run too much if you do the labor, and it is just wrench work, not alot of engine specific knowledge is needed.

Heads should go to machine shop to be surfaced, cleaned and pressure tested.

If your motor isn't already a ffv version then replace the heads with the ffv version engine vin code 2. They are a direct bolt on. They have smaller 47cc combustion chambers compared to non-ffv's 49cc and are of improved design that is less prong to cracking. They use smaller 7 mm valves and conical springs. New head bolts are mandatory. Don't skimp on machine work or cleaning. Patience is your friend. Don't rush your repair. Take time to plan what you are going to do and have the necessary tools and parts readily available. It may seem overwhelming at first, but if you follow these simple suggestions you'll soon find yourself at the end of a job well done.

It should be noted that not all of the FFV engines had the special heads. I believe at some point, Ford just started using the regular head castings on all engines. What you listed is true of the special heads, but it's important to consider that increasing the compression ratio with a smaller combustion chamber just makes an engine that likes to "ping" in stock form even more likely to do it. I'd definitely suggest polishing the combustion chambers if you do this, as it will give the carbon fewer places to stick, and cause fewer hot spots.

Here are mine for example:

That for sure!!!

And new head bolts!!
