Engine Diagram?

[Doctormario777]

Does anyone have an engine diagram for the 2.8L? I'm trying to find a leak and I know the general area where it is, but an engine diagram would help me narrow it down I think.

What kinna leak?

 

[Doctormario777]

It's an oil leak. It's somewhere near the distributor, but I don't think that's what it is. I just can't see back there.

The O-ring on the distributor, valve covers or the intake manifold. You can try snugging down the valve covers the hard ones are the two on the passenger rear if its automatic tranny the valve cover bolts are also the studs to hold the tranny dipstic in you need deep metric sockets to pull the bracket off first then snug down the valve cover bolts. It`s not uncommon for the intake manifold to leak out where the heads mate to the block in the valleys is another common leak. What you can try there is take a rag and clean that area real good with a good fast drying solvent.squirt a bead of permatex #2 in the areas all three meet head, block and intake and with your finger squish it in the valleys as best you can. What that does is makes like a plug inside the valley if you do it right. Have you changed your PCV lately if not change it with regular tune ups also change the breather filter inside the air filter housing that will slow down the leak also it keeps pressure from building up in the crankcase.

I really appreciate all of your help.

If changing the breather filter will slow the leak, if I took off the air filter and ran it, would I expect to see the leak be less?

I changed the valve cover gaskets and checked them thoroughly today with UV dye in the oil. There was no green anywhere near the valve covers. It runs down behind them. I just can't get a good look back in the engine to figure out exactly where.

The breather filter is the little media typ filter on the side of the air filter housing and connects to the oil fill/breather cap. Looks similar to this http://www.ebay.com/itm/NOS-PRO-GAU...Parts_Accessories&hash=item27bf281e71&vxp=mtr The new PCV will get rid of most of the blowby that makes it leak more oil from crankcase pressure. It can be rings and or valve guide seals creating posative pressure in the crankcase. Never run the engine without a air filter the little filter media in the breather collects the oil and it drains back down into the engine. If that media gets plugged up the crankcase cannot breath properly. Change the PCV, breather filter and air filter regularly. Breather and air with oil changes and PCV with spark plugs, cap and rotor. The PCV being the most neglected it costs around $8 but if not working correct it actually cost in the hundreds in fuel economy. The PCV cannot be cleaned just change it!

Any idea what the cost of the original air cleaner housing costs? Previous owner on my 84 Bronco 2 put some other air filter on it and its junk, not to mention it left the oil fill cover and the vapor hose just open to suck in unfiltered air. Thinking the salvage yard is my only place, but if anyone has had to buy a replacement housing lately what cost am I looking at its the 2.8L V6 BTW.

wildbill; have no idea...but I've been hitting up locals on craigslist that are selling parts vehicles for the parts I'm looking for...but most folks tell me the local salvage yards are the best bet.

I'm thinking once I get my Bronco 2 out of the shop next week I'll make a trip to the Pick A Part and see what all goodies I can come up with since the bronco 2 and ranger's 2.8L's shared the same components I can look at both which broadens my hopes of finding what I need.

It's been at least 10 plus years since I've seen any 2.8L V6 vehicle in a salvage yard in my area. If fact, I'm not seeing many 1983-1988 Rangers or Bronco II's anymore in yards.

I was around Sheppard AFB about five years ago and went to a salvage yard. They probably had 20 plus Rangers and Bronco II's. Of all they had, they only had like two that came with the 2.8L V6.

It's just difficult locating OEM hardware for these old trucks.

Around here anything with a carb is the first to go into the crusher it`s all a matter of timing.
