Do I need to replace valve lifters after having the cylinder head rebuilt on my 2001 Toyota Camry
Hello.
I am working on replacing my Head Gasket. After taking everything out, I resurfaced the Head and decided to do a VALVE JOB. I cleaned and lapped each valve to its own hole and now it is done.
I made sure to keep each valve lifter organized to put it back in its corresponding hole. My question is,
Do I now need to do something to the lifters now that the head is resurfaced and the valves have been lapped?
Can I simply put the lifters back in place?
If I mix one up, what can I do to correct the error?
Thank you.

Experienced mechanics share their insights in answering this question :
Hi there. When you have the cylinder head rebuilt and a valve job done then that will change the height of the valves in the head. The lifters are set a specific thickness to offset the depth that the valves are at. The valves will need to be set to the proper clearance using the correct lifters. With that being said you cannot mix them up and just install them without having issues. This should have been done by the machine shop when the cylinder head was rebuilt.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The lifter may be having problems with a sticking check valve, dirt, wear or other problems. If your car has a faulty hydraulic lifter, replace it as soon as possible to avoid further damaging your engine. In most cases, a faulty hydraulic lifter will simply need to be replaced.
The most obvious symptom of a faulty hydraulic lifter is the noise it creates in your car`s engine. You can usually distinguish the faulty lifter by the distinct sound. Instead of a knock or ping, a faulty hydraulic lifter will usually make a sound more reminiscent of a tapping sound.
No Hassles! Lifters alone can be changed without changing the camshaft. Camshafts are costlier than lifters and are thus made tougher to last longer.
Lifters like good oil change schedules and can last over 100,000 miles. Lots of things have an effect. Being hydraulic helps. Some noise is normal.
A properly maintained 2-post or 4-post lift can last decades. It`s not uncommon to find a used 2-post or 4-post lift for sale that`s 20, 30, or even 40 years old.
If you hear lifter noise, get it checked out. Sometimes they`ll hold up for a while, but if it`s bad enough the lifter could shatter. If it`s caught early on, a new lifter is all you`ll need – if neglected, a lifter can ruin a camshaft or entire engine in no time.
You may be under the false assumption that a solid lifter camshaft makes more power than a hydraulic design. That is not true in a pure sense. A solid lifter has the potential to follow a more aggressive camshaft lobe and also to work effectively at higher engine speeds.
It is possible to run hydraulic flat-tappet lifters on a solid flat-tappet cam, and hydraulic roller lifters on a mechanical roller cam. The rules in some racing classes restrict competitors to running hydraulic valve lifters.
Don`t doubt that someone has already answered this but new lifters on an old cam is OK. Old lifters on a new cam is a bad thing. The lifters wear into the cam and all cams are a little different. The lifter is the part that is made to wear the cam is not.
Because roller lifters don`t slide and generate a wear pattern, you can reuse those factory lifters on a brand-new cam and no one will accuse you of being a roller bonehead.
Faulty hydraulic lifters will usually results in the failure of other features and components, including the rocker arm, the valve tip and the push rod. If all these components fail at once, then that can result in major work being required when it comes to your vehicle`s engine.

I have a 2002 toyota camry LE engine wich i want to use on a 2004 toyota camry XLE .is my 02 toyota camry engine compatible ?
ANSWER : Hi there. Assuming that both engines are the same size, the compatibility of "fitting" should be OK. However, since this is a service we don’t offer, we’re not best suited to provide the best advice on this. I can tell you that a common problem have with replacing motors is communication with the ECU. In most cases, it will require reprogramming by a specialist in order for all the systems to work correctly.
Do i need to replace the receiver drier and/or the expansion valve when replacing the condenser assembly?
ANSWER : Replacing the system drier is absolutely essential. If the system has been open to the atmosphere (due to the leak in the condenser), the desiccant in the drier has been fully saturated with moisture. As far as the expansion valve, replacement is not normally implicated in a leak repair, in your case a leak in the condenser. To justify replacing the expansion valve, there would have to have been a diagnostic performed which proved a fault. If no diagnostic was performed, and there is no evidence of a fault, then it is pointless to replace the valve. But, again, drier replacement is absolutely essential. To add the drier to your order, you can simply add a note to the mechanic in your order and/or add it as a service (you will see a link that you can click on to "add services" or write in specific services). If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
When replacing the AC Compressor, do I need to replace both expansion valves as well or just the front
ANSWER : Hi there. Anytime you replace major air conditioning system components like the AC compressor, it’s recommended to purchase all supporting hardware and replace it at the same time. AC works as a series of individual components working efficiently together to create cool air that flows into your cabin. As such, if you’re replacing the front expansion valve, it’s a good idea to replace the rear at the same time. This increases overall efficiency of the system, reduces the potential of small component failure and allows the parts you replaced to last longer.
to replace a #4 cylinder exhaust valve lifter, do you have to do anything with the head gasket?
ANSWER : Hello. If you’re replacing the lifter with the cylinder heads attached to the block, you shouldn’t have to remove the cylinder heads or do anything to the cylinder head gasket. However, if the reason you’re replacing the lifter is due to excessive smoke from the exhaust, that symptom may be caused by damage to the gasket, which is why you should always replace the gasket as a proactive measure anytime you’re working on cylinder head hardware. It’s also a good idea to complete that job away from the engine, as it’s possible to drop debris inside the oil galleys. If you need help, an expert from YourMechanic can inspect your exhaust system and make the necessary repairs.
I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.
I have a 2001 Toyota Tundra 4.7 V-8. When replacing the valve cover gasket, what should I torque the valve cover back to when rein
ANSWER : The valve cover bolt is tightened to 60 inch pounds.
I just replaced my brake master cylinder and the brakes still feel soft. What do I need to do after I replace the master cylinder
ANSWER : From what you’ve described you will have to bleed your brakes. Also, I believe you may have a leak in one of the lines. You may want to use a wrench and tighten the lines a little more. If you’re unable to fix this yourself, consider YourMechanic, as one of our mobile technicians can come to your home to bleed your brakes, diagnose the Check Engine Light, and help you make the appropriate repairs to your car.
