SOURCE: head gasket on my 1990 toyota V6 3.0

I would highly recommend that you go to the local parts store and purchase a Haynes Manual for your vehicle, they are around $ 25.00 Canadian. As when you do your head gasket you wil need to remove your timing belt and this is a procedure in it's self. then you will neen certain torque settings. This manual will provide you with all of this information step by step. they are designed for the do it yourselfer. They also cover many other issues that you may come across through out the ownership of your vehicle. I know that the last ting you need is an added exspence but these manuals are well worth the small investment. There is a site that you can find hrough google search that you can find factory service repair manuals for your vehicle, however they only have a layout for a 4 cylinder engine in there drawings and this is alot different then the 6 cylinder. As the procedure for repairs is totally different. I hope that this helps and that you take the time to rate any solutions you receive. Good Luck.

SOURCE: 1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

SOURCE: i want to replace my head gaskets, 91 v6 3.0 4x4

It's a big job if you've never done one before. If you have and are familiar with this type of thing it should take about 8 - 10 hours. I strongly suggest that when you do you take the heads to a machine shop to check them over and HAVE THE VALVES ADJUSTED! They use pain in the neck shim system that has to be adjusted after 60? k otherwise you'll burn a valve.

The 22R engine is one of the best engines Toyota built.

With the head off, you should have had the head gasket surface machined and the head checked pressure checked for cracks. It seems you did so.

I can only assume, you MAY have put the bolts back in without bowing out the cylinder block bolt holes before installing the bolts. These bolt holes fill with oil and antifreeze when you remove the head.

Doesn't matter how careful you are, the bolt holes always fill with fluid.

If so, the bolt torque would be reached before full clamping of the cylinder head. Worst of all, the block could have been cracked by the hydraulic pressure in the bolt hole as you tightened the bolt.

1987 toyota pickup with 22r keeps blowing head gasket


Your head bolts are stretched, when it got hot it weakened the metal in the bolts which means that the bolts cannot hold the needed tension on the head. Replace the bolts and you will stop blowing head gaskets. Also use Genuine Toyota head gasket, It will be a bit dearer but they are much better than aftermarket options.

How do you disassemble a head gasket for a 2004 toyota camery?


replacing a head gasket is a major repair and really should not be attempted if you dont have adequate knowledge and experince withthe process. That said, the head gasket is sandwiched between the cylinder head and the engine block. It requires removing everything from the top of the motor, then removing the cylinder head itself. The old gasket must be completely scraped off the head and the top of the block and any adhesive removed as well... The new gasket is placed on the top of the block in it correct place. Each side of the gasket must be covered with a thin coat of gasket compound. The place the head on top of the gasket, sandwiching it in between and replace the head bolts and torque them down to the required torque. Replace everything removed from top of motor in reverse order. Keep in mind that in replacing a head gasket, it is entirely possible that your problem may be the head itself instead of the gasket. While the head is off, take it to a machine shop and have them inspect it and if its needs it, have them repair it. Again . this is not a do it yourself job.

I have a 2003 Grand Caravan 3.8l that is loosing coolant


1st check the condition of the oil by checking the dipstick. If the oil looks milky then it's a head gasket issue. If oil is ok, refill coolant, start vehicle and let it run for 5 to 10 min. If you notice alot of white steam coming from exhaust then it's a head gasket. After vehicle reaches normal operating temperture, shut vehicle off. Now you're gonna have to check each individual spark plug. If you find one that's wet from coolant then you're gonna have to replace head gasket.

White coloured engine oil, overheating


White oil means water or coolant is leaking in via Head Gasket Failure or a crack in the head. Along with repair - be sure to have each cylinder compression tested to see if there is a crack that has developed.

Engine check light read p0171 and p0420, noticed a leak of engine oil on cylinder 2 area of head gasket when checking the sparks plug, is that the cause?


P0171 code is described as: lean condition bank 1, oxy sensor 1. If your vehicle is a 4 cylinder, which I believe it is.. you have got a lean air/fuel mixture being found by the ecm(computer).This can be caused by several things. The first of which is a possible vacuum leak at or near the intake manifold. This can also be caused by a MAF(Mass Air Flow) sensor problem or even by something as simple as a clogged fuel filter. This lean condition could also be the cause of the P0420 :described as a catalyst efficiency problem. It would be best to have the vehicle taken to a reputable repair facility that is capable of engine performance diagnostics and have them run tests for these codes. The gasket you mention is most likely a valve cover gasket not the head gasket and would not cause these codes. Although you should have this leak fixed before it becomes a problem.

Hope this helps..
