I found this online:
I discovered yesterday that this 3.8l has 2 different intake gasket thickness's 3 or 4mm. I found thru here that intake gasket failure was common on the 3.8l. They saided that they improved the gasket making it thicker.
So I'm gonna go ahead with the 4mm. Let us know how it went for you.
Yes, there is a gasket in there. Felpro P/N 70415 for models w/o an oil coller, Felpro P/N 70801 for models with an oil cooler. Now if you can just get the filter out of the way you're golden!
They have problems with yhe intake manifold gaskets. Felpro has a improved set that do not leak.
Which plenum-intake or. . . .
The oil filter gasket is built into the filter itself, so just by changing the filter, you always get the new gasket.
Could be the head gasket. Very common problem with this engine and model year Windstar.
Never have seen a bad head gasket on a 3800 engine. The upper intake will leak coolant into the imtake ports and a greedy mechanic will tell you it's head gaskets. You may need to replace your oil pan gasket with a felpro perma dry gasket, cost more but worth it.
sadly u cant get another head gasket for an aztek so you can either get anothers head gasket and try to fit it in(try a gm kind) or scrap the car.if you sell the car you can only get like $900 from it so there is no point
They are an older style of gasket. Mainly found in years below 2000. Its often the OEM replacement for 90's cars. If you are able to, go with MLS gaskets. They are far stronger and will generally last longer. But you would probably be ok with graphite gaskets.
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
No - the head gasket repair can be done with the engine still in the vehicle.See "Related Questions" below for more
This would be a primary symptom of a blown head-gasket.
You should use whatever the car manufacturer calls for...some want paper, others rubber or plastic, and still others want you to use sealant.
Maybe a head gasket?
90% sure of it. There is a known circumstance I read about once that could result in oil getting into the engine coolant... Had to be one of the Windstar forums or here at WikiAnswers, since the early 3.8l Windstar engines were so prone to head gasket leaks...In the meantime and back to the more common causes... It could be either a bad gasket or a warped head. Either way, the gasket is going to be replaced.See "Related Questions" below for more
either a blown head gasket or cracked cylinder head
The head gaskets must be replaced. This is a major repair that should only be undertaken by a professional.
if its the 3.1, 3.3, or 3.8 engine labor hours average 4.5 hours
Yes as long as you buy a name brand. Purolator, & Wix are excellent filters. Felpro is one of the best gasket manufactures. Avoid Fram filters. Toyota does not manufacture these parts. They are manufactured by a supplier such as the above.
A head gasket is only one of the many gaskets in the engine. Each has a separate function and failure by any one gasket will result in different type of leakage. A head gasket failure is perhaps the most disruptive.
The head bolts to the block. The head gasket goes in between the head and block to seal the head to the block.
Yes. The head gasket forms the seal between the engine block and the head(s). The valve cover gasket seals the gap between the valve cover and the valve train it is covering.
Maybe, it depents on the brand of gasket you are using, Victor Reinz makes a 350 specific gasket, most others brands are actually the larger bore (about 4.20-4.30) 389-455 gaskets. Measure the cylinder opening on the gasket. The 389 has a 4.060 bore the 350 is only 3.88. Make sure the gasket opening is at least 4.060 so it does not hang into the bore of the 389. If it does it will fail VERY quickly. The easiest way is to just set the gasket on the 389 block and see if it is the same or slightly larger than the 389's bores. Otherwise the gaskets are the same. The Felpro 1016 is a very good gasket for Pontiac 389-455 up to about 12.5:1 compression. after that Cometics are a good idea.
Felpro makes an excellent retrofit gasket for this application. Follow the provided instructions, but also use a thin coat of High Temperature RTV on both sides of the gasket prior to assembly to maximize sealing. Valve cover and head surface must be clean and grease free, and the cover must bolted down before the RTV sets to seal properly. Replacement is a simple bolt off/on operation and shouldn't take more than 30 minutes to do.
For the 3800 the pan bolts should be torqed to 120 IN pounds in accordance with the GM shop maintenance CD-Rom's. Use the felpro higher priced gasket to avoid a repeat oil leak. The factory ones will leak like the cheap felpros.
Too many steps to list here. Purchase a repair manual for that vehicle from your local auto parts store.
