Hi guys,
I am fairly new here. Found this forum quite some time ago and got few hints for my since then.

I drive Toyota 4runner with 3L engine with 2lte Cylinder head with turbo. It worked fine till couple weaks ago my radiator cap got old and drained coolant out, so basically I am sure my cylinder head has a crack in it. The hoses are more under pressure then they used, thats how I know.

Now my problem is, because of my location (Tbilisi Georgia) I cannot get hands on Genuine parts without overpaying.
I was wondering if I could fit 5L head cylinder to my 3Lengine block? as far as I searched and read, there are no mechanical differences other then fuel injection system. I can get my hands on good 5L cylinder head for a good price you see.
If it doesn't fit, please provide where can I order the mentioned cylinder head for my poor baby?as i see Ausies and Canada loves these cars. I am offered the chinese cylinder heads for price of 300$

Thanks in advance for your help.

George

From what I've read, the 5L head won't work on the 2L/3L series engines. I think the cylinder head is taller, so the timing belt does not fit. Can't use the 2L/3L timing belt as it's too short, and can't use the 5L as it's too long (I think the 5L block is taller too). Something like that. I read it on the this forum years ago: https://toyotasurf.asn.au/forum/ .

After some digging I found that 3L and 5L cylinder heads are interchangeable. The difference is in the block height only. I found the supplier in Australia. Will install it and update here.

Probably a long shot but would be cool to get an update on this install if the OP is ever active here again.

I believe the 5L valves are larger than the 3L, but uses the same cam. Looking at pictures the passages all look like they *should* line up.

Hi,

I will of course update the project here. By the end of the August my 5L engine head will be delivered. I will install it early autumn and will try to photo the progress.

That would be great, thanks! If you get a chance maybe check the valve dimensions against your 3L too ...

And FYI I did look up all the timing belt PNs for the 2LTE/3L/5L and they all are replaced by the same number, so that shouldn’t be an issue

I have checked it several years ago, and they were exactly the same as I remember. I will confirm it as soon as I dismantle my engine and put he two heads together.
