Hot Valve Cover/ Temp Guage, Oil Leak, o2 sensor

deeeeeeeeeeleeeeeeeeeeettttteeeeeee

Wheres the pictures at??

any help anyone?

Better pics are needed. Interior pics wont help any of us to help you. Try an 02 bung may help if its throwing a code. But with out good pics its practically impossible to help you out.

your throttle cable is fine its suppose to have a lil slack/play in itt…puttin it tight could partially keep your throttle plate open and actually stretch out the cable within timee

alright cool thanks. now if you guys could answer my other questions ahhaa

im just really worried about the valve cover being so hot.

Blown head gasket maybe? ive never experienced that before but if you think its coming from between the block and head that could be it. Do a compression test or leak down test thats all i can think of.

  1. Check your coolant levels and see if there is oil in your coolant. if it is low fill it up, if there is oil in coolant, odds are you have a bad head gasket.
  2. Park the car overnight with a piece of cardboard under the engine, in the morning check the cardboard fir oil that dripped off.
  3. As far as the valve cover goes, i say pull it off and inspect your cams. try loosening them and re-torquing them to spec(get a manual if you dont have one they are valuable tools). i suspect that they are on too tight meaning oil wont lube them and as a result it gets hot.
  4. I believe the o2 sensor is behind the block on the exhaust manifold. you can see it best from under the car.
  5. And just so you know, there is no gasket between the block and transmission.

yeah sorry i mean between the block and head. do you think it would be hard to get it off and replace that gasket? (for someone whos learning) haha lemme know what you think!

Yes it may be hard for somebody who is just learning. Just check everything I told you and/or the compressionand leakdown tests before we jump to conclusions. Post up anything you find out.

Your overheating could also be caused by something as simple as a sticky thermostat. But you need to do the simple checks lawngnomeslayer first. Are your fans working properly? If you keep letting the car get too hot, you will cause some serious damage. You also need to keep oil in it and not let it “get really low”.

if the engine’s been rebuilt, the rings may not have completely set yet, causing burning of engine oil. any blue exhaust smoke under acceleration?
as for your overheating, what is the coolant level at? is it dropping?
let the car idle until it reaches operating temp. when it starts to overheat, check that the radiator fan is coming on. if it isn’t, there is a problem somewhere in the fan circuit. ie fan switch, relay, fan motor, wiring…further testing would be required.
if it is coming on, you may have a sticking thermostat, among other things. when they did the rebuild, they may have went with a low grade t-stat. when you check to see that fan is coming on, just as the engine reaches operating temp, feel the upper rad hose (the short one leading from the engine to the top of the rad). if it feels cool, the t-stat is sticking shut.
also, you should try bleeding the system. there’s dozens of write ups in here on doing that.
if you are losing coolant, you have a leak in the system somewhere. it will be either a hose or gasket. easiest way to test would be to install a pressure tester. pump it up to about 15psi and look for the leak. fondle all the hoses. make sure to look around the back of the head as well.

how does your heater work? it blow good and hot at operating temp? do you smell sweet coolant in the cabin?
are you blowing any white smoke from from the exhaust? if so, does it smell kind of sweet?

you don’t have to be extremely experienced to perform these checks, but if you have a family member or friend who is somewhat mechanically inclined and understands how these systems work, that would definitely help.
check those items and let us know your results

and while your valve cover is probably getting hot due to overheating, i think the factory paint does act as somewhat of a heat sink. so that white stuff you have on there probably isn’t helping that “issue” much

now do u see whyy you should never buy a rebuilt engine for 4gs…just end up with too many problems…its best just to buy a bonestock car and start from there

well, to be fair, his problems haven’t been identified yet. they may be small to nil.

i guess u havent seen his other threads he made…he already had to change his MFR…regardless he just spent 4gs and it hasnt even been more than month hes had it n hes haviing all these problems…

no, didn’t see any other threads. but TBH, a lot of his “problems” may be due to the fact that he doesn’t fully understand how these systems work. he may not communicate with us the issues correctly or know exactly what to look for, yet still try fixing them and end up causing more problems. happens all the time. it’s why diagnosing shit over the internet is pretty hit and miss. communication and clarity

yea true…all im sayin is try to never buy a rebuilt eengine thats alll

Come on. Don’t say shit like that, it makes you look like an idiot.

I think the bigger lesson is don’t buy an older car if you don’t know what you are doing and aren’t willing to learn. You are always buying someone else’s problem. Make sure you know what you are getting into. Now if someone rebuilt an engine, and then after 1500 miles is selling the car for less than they spent on it then you should question that. If their wife just got pregnant or they lost their job, then fine. But if they are that bad with their finances or they fucked something up and are trying to pass the buck, you should know it and be prepared for that. But don’t just make some asinine statement that you should never buy a rebuilt engine

If you were to buy one of my cars, it wouldn’t have any problems. Or if it did, you would know exactly what they were and how much it cost to fix when you bought the car. If something came up after the fact, you can bet your ass I would be there to help figure it out. That is part of being a decent human being.
