08 ram 1500 two wheel drive 4.7 flex fuel extreme bouncing when braking, the truck is smooth as silk at any speed until applying brakes (at any speed) you better hold your drink


things to check
if discs -check for good disc surfaces --not cracked or missing
if drums check for cracks or out of round
if solid front axle check for loose worn spring mounts / shackle bushes
if independent suspension check for suspension/ball joints
check for failed shockies
this affect is achieved when the brakes are applied and the wheels stop turning b and the axles are allowed to rotate in the suspension
when that rotation is arrested then the wheels skip on the road and again twist the axles
if it has abs breaking then run the fault codes as it may be faulty and not controlling the brake pressure as set by the foot pedal

What is affected when a car has overheated, I changed the gasket and skimmed the cylinder head


There are several items that are affected during overheating. If the engine has been running for a period then the pistons loose metal to the cylinder walls and cause a knock or rattle when started and run. Next the rings loose tension and will not work as designed. Excessive blow by --low compression and they may be broken. Rust scale that is around the cooling jackets comes loose and deposits in the cores of the radiator causing blockage and further over heating. Cracks can be found in the combustion chambers . The valve seat inserts in the head can be cracked or become loose. The head studs loose the tensile strength and stretch an should be replaced . If the engine has simply boiled and the engine was shut down immediately then the gasket and head shave should suffice but most engines run for some time without water before the driver smells or notices the overheat condition.

White smoke at exhoust and puch water out of the radiator


Blown head gasket or cracked head. I'll guess this happened after overheating the engine. The compression of the affected cylinder will blow coolant out of the radiator and coolant in the cylinder burning shows up as white smoke in the exhaust.12_24_2012_1_46_50_pm.png

2003 Jeep Grand Cherokee The fault code 302 reads from the ODB. the mechanic thinks this could be blown head gasket or cracked cylinder head costs $$$ to repair. However at same time A/C ceased to work...



Trouble Code: P0302
Does't sound like a cracked head to me I would take a look at all the vaccum lines.Also check the intake manifold and the egr system.
Cylinder 1-10 Misfire Detected
Possible Causes:


Air leak in the intake manifold, or in the EGR or EVAP system Base engine mechanical fault that affects only one cylinder Fuel delivery component fault that affects only one cylinder (e.g., a dirty fuel injector) Ignition system problem (coil or plug) in only one cylinder

Front head lamp replacement


When a headlight bulb goes out, you just replace the bulb, not the lens. Access is from back of lens assembly, under hood.
If the crack distorts light reflection, you will probably need to replace that, also. But, only if it's a problem. If not, the crack wont affect bulb life.

Over heating and steam coming out of exhaust manifold. No milky oil on dipstick.


sounds like blown head gasket or cracked head allowing coolant into exhaust ports. No water in the oil just means it didnt affect water getting into the oil ports. So the breach is between the water ports and the exhaust ports. It doesnt really matter. Its till the head gasket or the head itself. sorry..

Runs good when engine is cold, runs rough when engine heats up will a bad oxygen sensor cause this?


Generally no.
Oxygen sensors usually work or they dont .
If it was worn out usually you would see a change in fuel consumption.
It most probably is something being affected by the heat such as a cracked head which the crack will open up as engine gets hot.
It could also be from spark plugs and or leads breaking down, as overtime they are affected by heat.
other things affected by heat a electrical wires and connections,
Hope this was helpfull

My 89 cherokee keeps getting pressure built up in cooling system. have replaced overflow tank and new one blew out in two days. upper and lower hoses are flowing and i cant figure out what else to do. no...


You are likely thinking head gasket (no water in oil) and you are likely correct. A failed gasket will not always put coolant into the pan. It depends upon where the gasket has failed, what will be affected. That said, it does not need to be a head gasket. A cracked cylinder head can do the same thing, so, after removing the head, have it magnafluxed to make sure there aren't any cracks.(visually check the combustion chamber....most cracks happen between the valves...If you see a crack, don't bother having it tested)

Blowing white smoke when reved up.... boggs a little when accelerating, idles a little rough also.. its a 93 civic dx with a 1.5l


White smoke is usually caused by a cracked head gasket or cracked head, but some times it is caused by your brake booster sucking brake fluid into the intake through the vacuum hose. If your brakes are constantly going soft, or your brake reservoir constantly needs refilling then that will be your problem. Replacement will include both the brake booster and the master cylinder.

If the cause is a leaking head, you can fix it with sodium silicate (liquid Glass) which can be purchased in most pharmacies. You will need to remove your thermostat to keep it from sticking shut before doing this. Replace it after the smoke is gone.

Remember that the sodium silicate trick is more of a bandaid than a permanent fix. Also remember that sodium silicate is not a good fix for steel heads, and since yours is aluminum it should work.

BUT since your problem only occurs as you accelerate, I would suspect the brake booster and master cylinder.

Blown head gasket


I would change both, as well as use new head bolts. Make sure your heads are not warped or cracked, especially the one that is leaking. There may not be any need to change the head if it is not cracked. These are prone to blowing a gasket especially after 150K miles or so. It will not cost a huge additional amount to change both head gaskets since the engine will have to be disassembled down to the heads anyway. Hope this helps you, Rick
