Lifters in Engine!!!

Lifters in Engine!!!

i just took my car to the dealership to check my car cuz it was making a claking noise, and the people there told me it was the lifter, the thing is i have to leave my car at the dealership shop for about a week so that they can take aprt my engine and order my parts that i need!! That really sux alot, im gonna miss my car!!

That's a serious problem. It's good that the dealer is replacing it. In the meantime, drive the crap out of their rental. I brutally punished the Matrix they rented me before by doing peel outs, constant hard acceleration, heavy braking and locking, and even attempted to do a figure 8 before. Had the AC cranked the whole time of hard driving. That's what they get for making me leave the car for a week.

man thats bad, someone will end up buying that car, and thats just plain retarded for u to do somethin like that, seriously, thats something very immature.... im sure the dealer would rather not have ur car there.....

That's their problem, not mine. Toyota does a pretty good job with reselling their used cars. They don't sell crap used cars to anyone.

Who really drives carefully with a rental? I mean, come on. Unless you're some 60 year old, then again, they all drive pretty slow. I'm sure they drive the crap out of my car too when they had the supercharger installed, to make sure everything was working properly. There is also something called warranty....

what's a lifter?

lol ya what he said. haha

the lifter rides on the cam and acuates the rocker via a pushrod or dirrectly which in turn depresses and releases a valve. one lifter and one rocker per valve.

oh and if you ever do a cam swap, its a good idea to swap the lifters also to prevent galing or other unusuial wear form the mismatch.

for what its worth, i belive all OHC motors are lifterless

they are really more of a conventional, non overhead cam thing. my old 427 chevy was a good example.

so why did they tell you it was a lifter problem?

WELL THAS WUT THE PEOPLE AT TOYOTA TOLD ME AND I HAVE NEVER HAD A PROBLEM WITH THEM SO ITS COO, BUT I THINK I PUSHED MY LUCK WHEN THE SERVICE MANAGER (A VERY GOOD FRIEND) TOLD ME THAT ID THE PROBLEM WASNT FIXABLE THEY WOULD GIMME A NEW ENGINE AND OF COURSE I SAID I WANTED AN ENGINE OFF OF AN XRS!!!!!1

:shock: whoa :shock:

will they give u one haha?

i always thought no OHC cars had lifters???? just rockers run right off the cam lobes. maybe im wroung but still i know our engine doesnt have lifters... ive had my valve cover off it cam lobes directly to rockers. that doesnt make sense that the dealer told you it was a lifter. for the hell of it you should call them and say you just found out that your car doesnt have lifters and see what they say. lol

technically, in an overhead valve setup (OHV), the cam lobes have the lifters riding on top of the lobe. The lobe lifts the lifter, which pushes the pushrod up which rocks the rocker arm which presses down on the valve and opens the valve. That is for overhead valve assemblies. With overhead cam designs (SOHC AND DOHC), the camshaft sits directly over the valves. You have the valves and springs and the lifter (which is actually a valve tappet) is just a little metal "cap" sort of that sits directly on top of the valve and spring. It provides the cam lobes a smooth surface to roll on. The valve tappet is sometimes call the valve lifter - the terms are interchangeable. Technically, it's NOT a lifter, but we use the terms interchangeably. But whether an engine is SOHC or DOHC, it's all the same - there's no rocker arms or pushrods. Because OHC is OHC, whether it's a single or double cam.

My brother's old 1990 Nissan 240SX had the 2.4L 4-cylinder. It was only a 12-valve setup (2 intake and 1 exhaust / cylinder) - it was an SOHC engine. All the valves were directly beneath the camshaft so there were no pushrods or rocker arms. Just 1 camshaft, 12 valve tappets and beneath the tappets (or lifters) were the valves and valve springs.

if you could pay like 500-1k more over the 1zz hell yah i would.

WHAT??? That is what those cars are for... its to be expected!

This is why people under 25 aren't allowed to rent cars or have to pay a higher price.

thats has nothing to do with it. They look at insurance wise. Its more expensive to claim a 21-22 then a 25 or married person.

Actually, unlike DOHC engines which have an intake cam and an exhaust cam, with the cam lobes pushing down directly on the lifters, SOHC engines do have rocker arms; The cam sits between intake and exhaust valves so rocker arms are used to reach the lifters.
Your brother's SOHC 12 valve KA24 engine had 1.422:1 ratio rocker arms...
On Honda's 'Monocam' motorcycle engines, the cam sits on the intake valves and has rockers only for the exhaust valves...

...and the reason insurance is higher for a 21-22 year old than a 25 year old is the level of maturity and responsibility.
