6G Celicas Forums

Ok someone please help me I'm at a loss here. Pretty much every time I start my car it makes a rattling noise, also when I get up to about 3000rpm it makes the same noise until I shift or left off the gas and let the R's go down a bit. Anyone else have or had this problem and know what it might be? I pulled the valve cover to see if my valves are adjustable...they are not. I have the 1.8L 7AFE motor. Please anything would be appreciated. I have to get this motor to last at leaset until tax time so I can get my 3SGTE...

7a's valve adjustment is with shims on the underside of the lifters. there a pain and really dont have to deal with them unless your rebuilding. i know on mine the injectors are really loud. do you have a stethoscope? if so start the end and listen around with it at the fuel rail, valve cover, block. the reason i replaced mine 2 years ago was rod knock. keep an eye on it and how it drives.

Ya it's been making this noise for awhile. It started shortly after my ex was maxing out the motor in a parking lot....and he said the oil light was on the whole time... -_- ... So I know something is bent or something like that...

You can buy a set of feeler gauges for around $5 from the autoparts store. I know for certain on the 2.2L 5SFE you need the feeler gauge set that is specifically for valve shims( it has a 45° bend on the end), but Im not sure its absolutely necessary for the 1.8L 7AFE. You have to measure half the valves clearances then turn the engine over 1 full revolution and measure the other half.
If the shims are out of clearance and you decide to swap them yourself, You can then use a large screwdriver to push the valve lifter down so that you can use a small screwdriver and magnet to get the shim out. Next step is to use a caliper tool to measure the thickness of the shims that are out of clearance. You should be able to swap most around to get to the right clearance but you may need to order a few that you dont have.

Anyways its not hard at all, kinda tricky pushing the lifter down with a screwdriver though. A little bit of valvetrain noise is annoying but not necessarily a bad thing. Just try not to let it worry you, all of our four cylinders are noisy as hell.

Cool thank you. I will try and see if that works. But yes it's very annoying. Especially when I'm right next to a curb and I can hear it. Just being 1 of 2 Celicas in Tucson's car scene...I don't wana make us look bad infront of all these Honda kids ya know.... :-/

Now that you mention it running low on oil. It could be a bad bearing, like i said with mine was rod knock.

Ya I think I'm goning to try and do the bearings and see what happens. Hopefully this weekend I can buy them and get it done quickly. I'll deffinately let you know what happens...

How good are you with cars? Its alot of work to strip down a motor in the car. Easier to pull it out

Kick him in the tender berries, he does not deserve the right to procreate.

What an idiot... Could try pouring in some Rislone, it usually does a good job of quietening an engine.

I've been doing oil changes every 1500 miles and using Lucas as one quart. ****s getting expensive tho lol I'd rather just fix the problem now than bad aid it anymore. My poor baby.


Yes I do agree. Yet another reason why he is an EX lol ^_^

I'm decent enough with cars. If I have to pull the motor then so be it. I have a friend with a cherry picker so it's not a big deal. Plus it's not like I don't have a grip load of guys who are all gona be spectating anyways. I already have one guy who is going to help me do whatever I need to do, he just points and tells me what to do next so that way I can learn this stuff...I had a basic idea now it's the getting dirty, greasy and sweaty I have to look forward to lol I'm excited ^_^

WOW! always fascinated to see a girl getting her hands dirty. Not something you see everyday. Depending on your time frame and money situation, i would suggest what i did and am currently doing. Get a spare motor so you can either just drop it in, or do a propper rebuild to ensure everything is ok. in 4 hours you should have the old one out and the new one just about all hooked up. To rebuild a motor takes ALOT more time due to measuring and machining if necessary. Just pulling the crank out to replace the bearings takes 6 hours(pulling motor, and actually getting the bearings in your hand). My 7a is pissing oil past the rings and valve stem seals, so i bought a spare, doing a complete build top to bottom(trying to prove the 7a na can make some power), and when i have everything ready to go ill spend a saturday putting it in. Weight your options. Its good you have friends to help, and 6gc is always here.

Ya I have been debating heavily on what my next move is...either I save up and get the 3sgte(which is what I really wana do, there's a guy in town who has already done the swap) or get the 2.2 gt motor and trans and throw a turbo on the for now till the motor pops and then throw another motor in there. I'm not sure yet. I just wana put these Honda kids in their place ya know.

Could look into swapping in the 1MZ-FE V6, a few people on here have done it. Personally what I would do, cheaper and parts are readily available.

Is there a forum for this swap? I'm intrigued....

Members kurt95gt and Smaay have done it, that I know of. I'm sure either would be happy to help you out.

sweet muchos gracias senor lol

Welcome.

the noise, is it coming from the top of the engine (the head) or from the lower block? Mine make noise from the block cause it has a bad rod bearing in it.
