Toyota 4Runner(4x4) 3.0 V6 engine (How to Repair valve cover gasket/leak).2/2

[kuvuakoj]

i was wonder i just bought a 89 toyota pickup from my in law is a 3.0 v6 like yours, are they running timing belt or chain on these?

[bmwmsport11]

@kj7687 agree, but what makes mine soo bad is that the truck I just got is rusted like hell and the owner before me didn't know a single shit about it. The oil in it is 5k old. So I guess they thought its soo reliable, that they don't do a thing to take care of it.

[hondaslave]

these are the worst engines ever made,,,,my moms 4 runner has had the heads replaced twice,,, and my truck three times....i finally junked both for $300 after spending over $4k

[kj7687]

@hondaslave The worst engines ever made routinely go to 200 or even 300k miles without being rebuilt? Interesting...

ok i seen u took the intake manifold off did u have to buy a new intake gasket. i want to replace my valve cover gaskets as well. What other gaskets are you going to need besides valve cover gaskets when doing this job.

[SteveXnycperformance]

@slipknoter106 Yes you with need a fel-Pro Intake manifold gasket kit.it comes with all the parts and sealer.

I have a Valve cover gasket leak..It blew white smoke out of the exhaust pipe,I smelled anti freeze and shut it down.. I confirmed that antifreeze has gotten into the oil,But I believe it did not overheat extremely. Are we talking about the same repair here?..Any reccomendations?

[fearknotmudtones]

Hi, I'm looking at doing mine myself in a few weeks. What advice do you have for me that you did not mention in the video. My research so i found.

Use only gen toyota gaskets

I will be changing the intake gasket , pcv valve while i'm at it.

I also heard to use some sealant on the corners of the gasket, and to tighten the vavle cover bolts in a spiral pattern. If this correct and do you know of any other information out there that will help me guide through this process.

Thank you.

Hi Steve, i have a question for you im a owner of a 92 Toyota 4Runner with Auto transmission, 4x4 V6 3.0L SUV i've been hearing weird noises when i start her up when she is cold, when she starts the RPMs are between 800 and 900 rpm, then after the noise dissapears after 5 seconds the RPM goes up to 1100, what it could be?, btw when im at the highway at 80kmh she wont shift to 4th, and the RPM range is in somewhere 3600 and 4000, then after a while it doesnt accelerate and dies. what could it be?

[hehawaiiau22]

You know the hoses that you said to label...forgot to label them. Please help...especially with the evap hose.

[SteveXnycperformance]

@hehawaiiau22 Contact your local library to provide the Toyota service manual with a year make and model. 

[hehawaiiau22]

where does the evap hose connect to?

[REDT4R1]

Do you have any vids on how to swap a 3.0 to a 3.4??

[SteveXnycperformance]

@REDT4R1 you should consult the service manual. If the 3.0 and 3.4 came install from the factory,then it is possible to perform the swap with ease

[TheBensalenkkari]

does anyone know what Toyota's Diesel trucks have a chain-used camshaft? Thanks.

[Luna7ick]

what is a fair price to pay to have these gaskets replaced?

[hondaman338]

okay this doesnt pertain to anything in this video but i own a 1991 toyota pickup its got the 3.0v6 and an automatic transmission and it will not kick in to overdrive until it is running at normal temperature and then when it does get up to this temperature the truck will randomily kick out of overdrive sometimes do you maybe know the problem?

[SteveXnycperformance]

Does SES(engine)light appear while driving?scan it for a code.The cause might be the over-drive solenoid. Inspect the transmission fluid for discoloration and burn smell.I would recommend replacing the trans fluid and filter. Add on bottle of Lucas Trans slip to condition all seal and clutch.

[hondaman338]

@SteveXnycperformance no the sensor doesnt come up but i will try replacing the fluid and check out the lucas oil thanks alot

[slaminaevil6]

I have been trying to figure out where a vacuum line goes(it's in in your video at 2:35 located from the air intake. closest to the "V6 3.0 EFI"). I have been combing the internet for information on my 1994 4Runner. I have an oil leak exactly where this yours seemed to be(the 4 and 6 cylinders aren't firing). i know it's one of many problems, but it would be awesome if you could get back to me.

Thnx 4 the video!!

[SteveXnycperformance]

@slaminaevil6 It will be best if you consult the Toyota service manual for a vacuum diagram.Oil leaking on the spark plugs will not cause a Mis-fire.You might want to inspect the distributor cap,rotor and ignition wire.Also remove the spark plug and inspect the electrodes and make sure the porcelain is not crack.Toyota(imports)are known for burn oil at hi-mileage and this will cause a foul spark plugs and O2 sensors.you should also make sure the Mis-fire is not cause by the 4&6 injectors

[slaminaevil6]

@SteveXnycperformance I have the Haynes manual, which is helpful but I still cant find that specific line. I also have replaced the distributor cap, rotor, ignition wires and spark plugs. This engine is old(220,000 miles) and needs a few things replaced(I'm finding cracked/worn electrical wires). I will check the O2 sensors and injectors next. Your video and advice are much appreciated!

[SteveXnycperformance]

Remember,the Mis-fire will occur if the valve seat are not 100% sealing the combustion chamber,And worn/stretch-out timing belt will cause this to happen. Please do a compression test on all the cylinder and compare all the cylinder psi. Psi rating should be with-in 5-10psi amount all cylinders.Does the ECM display(SES light)a issue?.A Mis-fire will cause a flashing SES light(dash cluster). Make sure its a Mis-fire code by using a scanner.

[SteveXnycperformance]

A faulty mass air flow(MAF) will also cause performance issue.Replace the O2 sensor at every 50-60,000 miles.ALL VACUUM LINE(air intake system) MUST BE AIR-TIGHT or the MAF senor will display a false data to the ECM,which will cause the engine to perform poorly.

[DevinL16]

hahah super vid. i have same runner and same 16v. loved the " i appear to be a professional, so i dont have to label"

[flaauli]

I have a 91 4runner and i just replaced the water pump, plus the timming chain and washers in there they told. Now my engine is vibrating and loss allot of power and engine is making noises. i took it back to them, but told me the engine cracked, but there is no leak or any dis-coloration of the oil fill cover or the dipstick.. I don't know what that is all about, but your feedback is appriciated. Thank u very much

[scabeba]

@flaauli Sounds a little fishy to me. The key is did it run bad at some point AFTER you got it back or was it bad WHEN you got it back. Either way, it sounds like the cam timing is off. These engines will still run, but will have a loss of power. Your repair shop should explain to you what "cracked" means. That deserves an explanation.
