SOURCE: Jerks going into 3rd Gear

You the beginnings of what is known as the reverse slam. If caught early enough it is fixable. However, most times a rebuilt valve body is in order. I do it for around $200. For the record any late 1992-2002 valve body will work, those are the type II. Type I won't work and is 1992-early 1992 years.

SOURCE: 2002 Saturn SL1 - Losing reverse and second gear

The simple answer is that there are two loose nuts in the transmission.

The output shaft nuts are loose. The are behind a cover that you can see through the driver's side wheel well.

SOURCE: Gear Shift very stiff, doesnt want to go into 1st gear or reverse

Continued operation like this and $100 would have been the cheap fix. If this is a hydraulic clutch, check the fluid level in the clutch master cylinder. Most take Dot 3 brake fluid and it will say on the cap. It is located on the fire wall near brake master cylinder

SOURCE: terrible rattling noise in engine when a/c turned

hi, there is a very common problem in these saturns with the upper front motor mount breaking and causing this rattling sound when in gear, that might be problem with the noise. you can check by placing the vehicle in gear(reverse or drive) and foot on the brake very hard, apply quick bursts of the gas pedal to make the engine surge. if there is a mount broken, you will see the engine lift up, or out, but you may need someone to watch from the side of the car to pinpoint the mount. now as far as the servie engine light, i would need to know the codes it produced from the pcm to help answer further, there could multiple issues in one circuit. post a reply to this thread and i will check again if you have the codes for me to look at and try to help you further there.

Problems with 07 tundra, engine light on, won't turn over completely without pumping gas pedal. Told it needs timing chain replaced

Timing chain controls the valve timing and causes running issues. It sounds like the chain and or chain guides are bad and you should NOT drive it that way as you can cause much more damage. Get it fixed and you should be fine. If it is a high mile car have them do a complete inspection of the vehicle before you spend any more money so you know if there are more issues.

Rod knock upon start

Not sure on model but to me sounds like its a dodgey valve lifter when the seals start to go they cannot hold the oil and when there under pressure they basically empty them selves hence when you turn the engine off and restart you get a rattle sound untill the valve fills again as long as the cars running ok leave it untill you have to replace them unless there easy to do sone are sone are a pain

2001 Ford Ranger 3.0L V6 Timing Chain Issue

if the quote was ridiculously high
the mechanic didn't want the job

you could take the rocker covers off and check the cam chain timing marks

first picture is the crank chain of that engine heavy duty one
front of the motor ......take a few things off
remove timing chain cover
and there is that one
second picture
there are chains kits for the cam shafts

as for engine not turning over

if motor is stuck solid and no movement back or forward
on the crank
oil pump may have failed and seized the engine

mechanic would be right
the original engine rebuild will be expensive because of the internal damage

if that is the case source a used motor and drop that in

I think you had better have a local shop inspect this for a failed engine connecting rod.

Turns over but won't fire

well the plastic piece are from the timing chain guides are either broken or ripped off,and the metal rattling was probably the timing chain,,i think the timing chain jmped or broke and broke the guides,if thats the car you most likely bent the valves in the head,,,i would remove the cam cover and the timing chain cover and see what you got,you may need a engine

Rattle in the valve now has no power and hard

pull valve cover and start checking your valve lash and if you do know how i would take it to a shop or buy a repair manuel and a feeler guage from your local auto parts store also check all the rocker arms and valve stems look for brokin valve springs if every thing looks good check valve lash.check timing chain or belt for abnormal wear if its a chain check and make sure its not to loose and if its a belt look for missing teeth on the belt this can cause very serious damage to your engine if its a zero clearence engine.

I would venture to guess that a timing chain guide broke and the chain chewed a hole thought the timing cover. The timing cover also has coolant passing through it where the water pump is attached. If you were running a multi viscosity oil, even it it were a 20-40 and got surprised by a zero degree day, I doubt seriously, it would cause that to occur. That series engine had problem s with timing chain guide failures. However, there usually is some chain rattle well before a disastrous failure. Most of my customers noticed the chain noise before it has caused catastrophic damage.
Sorry you have suffered such a loss. Good luck on your repair. A used timing cover would be the cheapest route. A place in Dallas called Bishops, buys engine cores, dismantles them, evaluates them, cleans the good parts up and sells them at very reasonable prices. They ship all over the country.

2003 Maxima Rattle / Rattling 1500 to 2000 RPM

what you are hearing is a spark knock or detonation. its not going to hurt anything or cause any damage. if you want to get rid of it than run out all the fuel that you have and fill up with super and see if it changes with premium gasoline. if you look at the fuel door on the inside, it sais premium fuel recommended. also stay with NGK (nissan)spark plugs. You may also need the r/h side rocker cover. the one by the fire wall. the seals inside the cover leak oil into the spark plug hole and you will need to replace it if you find oil in the hole. let me know what you find.

1989 Dodge Raider timing chain worn out, 4 cylinder? Bought a 1989 Dodge Raider and it rattles in the engine when it is idleing, A mechanic said it is the timing chain and not worth fixing just drive it...

I doubt it is the timing chain. More than likely it is the valves themselves, the seats wear out, and the lifters wear, so eventually the lifters don't pump up as full as they should, so it causes a gap between it and the valve, so it slaps the valve, also the seats wear, so the valve is kinda loose, so that causes a gap between it and the rocker shaft, so you get another slap. If the chain wore out enough to be hitting the block or front cover, you would be having timing issues because it would have to be pretty loose. You may also have a failing oil pump, so it is not suppling the right pressure, which is why you hear it at idle, because under load the pressure goes up and as I said it pumps up the lifter. This guy is a joke if he told you just to drive it till it blows, which would cause significant damage, Then you have to buy a what? use motor for $600 that is no better off than what you got? Then pay someone like this idiot $500 to install it? Right now you could probably rebuild the engine for about $600, and have a brand new fresh motor for your truck. The chain is not too difficult, you can do it in the car, but would be much easier out of it. The head doesn't have to be removed to do it, but you do have to take off the timing cover, which can be a pain, and possibly the water pump, all the engine pulleys, alternator, etc. So thats why I suggested pulling the motor. And, when it is pulled, it would be a great time to freshin it up with new pistons, rings, bearings, have the block done and rebuild the head.
