How to replace the head gasket on an 86 FORD BRONCO

A torque wrench to tighten the bolts to spec. Necessary tools to remove the head bolts. A gasket scraper for the rocker cover gasket and the head gasket.. If you have a blown head gasket the chances of a warped head is about 98%, so be prepared to have the head machined flat before reinstalling the head. You might want to do a valve job and replace the valve stem seals since you're going to remove the head. If you decide to do a valve job, you MUST do both heads or the engine will never run good.

Oil leak its not filter or oil pan ?? Plz help me out

Well the video really doesn't show much but you can start by popping the hood and looking at the rear of the valve covers. It could be a blown valve cover gasket. It could be a blown head gasket. It could be your rear mail oil seal on the crank, which would require transmission removal and oil pan removal. If you have a turbo on the truck it could be that you blew the turbo. Sorry I couldn't be more specific.

Xterra 05 bypass valve in the oil pump stuck - oil valve goes up and down

sounds to me like your rear timing cover gasket is blown out, and your oil pressure varies due to the leak. you will have to remove front cover and check the oil passage covers for gasket missing or blown. pricy repair, time consuming. have done dozens of those.

How do i replace a blown headgasket

To replace a blown head gasket requires a lot of labor on this vehicle. Its a v6, meaning you have 2 head gaskets to replace instead of just 1. It requires removing air cleaner, disconnecting battery, removing most of the accessories that are belt driven, removing the intake manifold, egr valve and tubing, exhaust manifold on both sides of engine, timing belt removal, valve covers, and a few smaller items. After removing everything on top of the engine, you'll have access to the cylinder head bolts. Removing them will allow you to lift off the cylinder heads. Before replacing the gaskets, you must send them to a machine shop to have the gasket surface milled true flat again. They must also be inspected for cracks (which will sometimes happen with blown head gaskets) which would render them useless.
If this is a vehicle you really like, perhaps consider investing in a quality used motor. Its less labor intensive, less repeat repair, and you may come out saving a few bucks.

Moisture showing at the rear of odd numbered valve cover...and milky looking condensation in the valve cover breather...there is no dipstick for this engine...the car doesn't run hotter than 180 and I...

The FIRST thing you need to do is get a dipstick. The condensation in the valve cover is most likely from moisture getting drawn into the engine through the dipstick tube. Not to mention that it is also drawing unfiltered air in that can mess with your air-fuel ratio and act like sandpaper on your internal engine parts.

Also, if you are afraid that you may have water in your oil, you can check for water in the oil by taking the oil pan drain plug out.

Blown head gaskets don't make the engine run cold, they make them run HOT! (Over 240)

Blown head gaskets also do not make things come out of the valve cover. The valve cover is ABOVE the head gasket. Gravity makes liquids run downhill. You most likely just need to fix an oil leak at the valve cover.

Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

Cannot remove right valve cover

Removing the valve cover won't tell you anything about the head gasket. Most if not all those hoses will need to be removed to remove cylinder head, so, if they are in your way, remove them.
First though, how did you determine that head gasket has failed? (symptoms)

someone has just reversed the valve covers swapped them from one to the other as far as the oil concern, sounds like you either have a leaking trans cooler in radiator or you have a blown head gasket
