WOW hats off my friend. Being a backyard mechanic myself I only have respect for your quality of work. I have done quite a few h/g myself but never on a Previa. Today my friend came over with his 92 Previa and after my diagnosis I concluded he needed a h/g job. Hence I googled and found your post. This is so enlightening I am itching to get started on the job. I am totally a hands on guy and you just made it look so much easier, thank you so much.

I stupidly assumed I had a starter motor problem and removed it, paid for electrical check (in-conclusive) bought new starter motor BEFORE pulling the plugs and turning the engine over, only to find I had a hydro lock situation going on and a blown head gasket, these engines are so resilient they seem to be able to run with a lot of bad things happening inside. Given lack of basic TLC to my poor, long abused Previa, when the head came off the abuse was very apparent with a big clean up job required to remove the caked on, almost plastic state, of the oil deposit everywhere, including the sump where the internal oil filter was 2 thirds blocked with deposit. After a big clean up and head check where a few minor cracks were noted I got the gasket done and all back together now with new coolant (not water) fresh oil and new filter the engine is running beautifully. Garage wanted to take the engine out, thanks to your video I took this job on myself at home, I was slow but only had to pay for materials and head check/clean so around $400. All thanks to your video, thanks so much for sharing your knowledge. PS...one thing to beware, when making that final tug to get the head off, I managed to snap the upper plastic cam chain guide somehow and had to get that professionally plastic welded and a bit of fiddliness getting it back on the metal rail base, so be careful as you pull the head away.

I have never seen so well explained step by step video like this one before You help me so much

I like your video, informative very straight forward and no confusion.

Thank you for a great video. I just followed it and is in the process of putting things back on. One detail: it isn't mentioned to remove the timing-chain tensioner right before replacing the head and chain sprocket, to make it easier to reinstall the chain back on cam sprocket. ( Samay mentioned this to me on FB )

Thanks. Very good work.

I loved it! It was awesome the way you explained it all very clear, just what I needed to get mine done. Now I feel more confident to tackle it down. Thanks

Very nice work you are a Master Mechanic +++ !! My 94 Previa just blown the head gasket I have little hope to get it done .

~Master Sam shares as usual! I understood it all of cource replicating another matter.

Wow 😳 this is an enormous Job, just for big wizards full of knowledge and experience... Thank youuuu for share...

Excellent work

Thanks a lot!

Great video!!!!

very nice video very instructive and detail video, I am going to do mine now.

Very nice work men

I'm going to do this job within the next few months, so that I'm a bit safer for some drives I plan to do. Thanks for this post, I find working on an engine mounted this way a little intimidating.

Well done!. Success!. Good jobs!..

Super!!!

Yes!!

Super👍

Great tutorial! I've watched several different 3rz teardown videos, but yours has been the most helpful so far. I'm in the middle of pulling a cylinder head and had a question (if you don't mind) -- Is it absolutely necessary to entirely remove the timing sprocket from the cam shaft? Or can the chain removed from the sprocket after pulling the tensioner? I noticed pretty much everyone completely removes the timing sprocket from the camshaft. Thanks!

شكرا.

I am getting ready to have this job done to my van. Do you have a contact number I can reach you? I have a few question such as replacement gasket OEM vs fel-pro and if timing chain components should be replaced among other questions. Thank you!

nice my friend

Great video!! I'm thinking of doing the same to my 96 diesel previa, where did you get the reconditioned head? And how much did it cost?

Do you have a shop? If so, how much would it cost to have the HG work? Thanks!

I have some decent mechanical abilities, I've pulled / rebuilt engines before, how long does this job take for someone who isn't experienced in previas? A day to remove the head? 2 days?

Hi there, 1. Do these engines commonly crack the cylinder head when they blow a head gasket and if so, can they be successfully repaired? 2. Do you use genuine Toyota head gasket or after market? 3. Is there any reason that you did not check the valve shim clearances after reinstalling the cams? 4. From your experience how often does the cam chain and tensioner need to be replaced in these engines? Thanks, Philip

I got a question, I forgot to set the 10mm screw locking the split great before taking out the exhaust came. How do I set that back?

amazing detailed work there...my supercharge emit slight tappet noise ..inside you can t hear it but once outside...its like a diesel engine...

Great video i dont have one but was interested in how hard it would be without a lift. Seems rough compared to regular engines spaces

I just started this job. This is super helpful👍. I'm going to lower the engine tomorrow. If you or anyone can see this, I was wondering, did you have to note how the teeth were when you pulled the distributor? My Corolla, you have to, otherwise you'll be left guessing on how it was... or you have to retime it.

Coolant leaking out of flex pipe. Is that sign headgasket is done?

My 800K mileage, 92 Previa also immobilized in my garage box for blown head gasket too. Only now I see the steps how to repair it. Thanks. Question: Do we need to plane the cylinder head surface everytime has been removed?

Exelent video, I just have a cuestión do you the head to the machine shop?

Amazing video, i just bought a 95 all track s/c and i fear the day it will be my turn to do this 😂

If you are losing coolant like crazy and you see a trail of liquid behind where the vehicle has been driven, suspect the water pump. These problems were hard for me to sort out; when a coolant reservoir overflows from the engine overheating, a trail of coolant on the ground can result. I replaced the thermostat and radiator cap first, both to no avail. If the three small tubular passages in the coolant reservoir are clogged, this will cause overheating. Any of these failures can then result in a warped block and a breached head gasket. So if doing a head gasket, consider the original cause of overheating. You may very well have several things to fix. Billowing white steam from the tailpipe IS NOT NECESSARILY a blown head gasket. A hydrolocked cylinder, which can be purged by removing spark plugs and turning over the engine, is still NOT NECESSARILY caused by a blown head gasket. Thanks to Sammy for this helpful video, although it makes a very difficult job look sort of easy, it is the best guide available.

Can anyone help me out? 1998 2rzfe. A small drill bit fell into the little oil port on the left front of the block deck that lubes the timing chain tensioner. How can I remove it? Please help me out guys. Thank you. Darrell

Caution: before removing the camshafts, observe the alignment divots, two on the bottom or exhaust camshaft, and on the intake camshaft. On my intake camshaft, there were THREE divots spaced away from each other. So use you paint pen to draw your own alignment mark across both gears. Do not rely solely on the divots on the upper gear.

What do you use to safely mark the pucks to keep them organized?

I got everything out, repaired, and back in perfectly following this brilliant video Samay, on my 1993 Previa. Just finished my second round of 90 degree tightening sequence, when my friend pointed to the old Chilton manual saying I should have squeezed a couple inches of gasket sealant along an edge in the timing chain compartment next to where the gasket ends before reassembling. Is this true? Or just a preference. I find nothing about it in any other literature. If true, I will undo everything and get a new gasket and head bolts and redo after laying the sealant in that area between the block and head. There are 3 rectangular cavities on the block side of the head on that edge. Perhaps this is just a precaution?

Where i can find service manual for this car, please?

Hello my friend, I am Osama from Iraq. He has a Toyota Previa, and the exhaust smells like gas. Even when I walk, the smell of gas is annoying. What is the solution? Please, I am one of the participants, your approved girls

I notice he doesn’t put any sealant on his head gasket. Is it not necessary?

hi there your engine use super charge or not?
