Right, suspected that, will look at that now. Took the RH cylinder head off today (took its time, I have a smashed RH shoulder and need help from my neighbour for heavy screwing). Before removing the cylinder head, checked all sparkplugs, all 4 sparked on demand as they should, and they...

I guess the best I can hope for now, with the new cylinder head leaking oil into the exhaust pipes, is that I spot something wrong/faulty with the gasket when I take off the cylinder head again. Since I now have new valve oil seals from the last round with the cylinder heads, would it be...

No, I did not reuse the gasket. The old gasket was Toyota original - only been used a few hours - since I changed Valve oil seals. The gasket used was a gasket (new) made by a Bangkok gasket maker using the original Toyota gasket as template. Re condensation wouldn't that come from all pipes...

Cylinders are numbered as follows; RH side: 2-fore, 4, 6, 8-aft; LH side: 1-fore, 3, 5, 7-aft. 1 pipe serving cyl 2 and 4 + 1 pipe serving cyl 6 and 8 1 pipe serving cyl 1 and 5 + 1 pipe serving cyl 3 and 7 Normal for the engine is to have invisible exhaust from all pipes. Idle speed about 400+...

thanks, yes I saw that, several kits for 30-40 USD, it doesn't heal itself, but its much less smoke from cyl 2/4 when the engine is up to 80/90 degrees just found out that the cylinder head gaskets are in stock here, will be delivered to my dealer on Monday, OK to have a spare set. In the next...

MORE SMOKE, FIRE ANYWHERE? Yesterday; weird indeed; replenished coolant a bit, startet like a shot! not running smoothly, rather heavy white exhaust from pipe servicing cyl 2 and 4, running on 7 cyl. some white smoke from pipe serving cyl 1 and 3 was there, automagic self repair over igh while...

I wouldn't, sorry if my usual mistreatment of English is unclear, what I tried to say was that I can afford a few hp down, but can not afford Nm down.

TOYOTA TEMP/PRESSURE SENSORS When the cylinder heads were purchased the scrapyard put some extras in the box, among those were two Toyota sensors, one looks like a temp sensor one looks like a pressure sensor. (I use my own sensor on my 1UZ) Where are the Toyota water temp sensor/oil temp...

SMOKE WITHOUT FIRE? My 1UZ is normally running with invisible exhaust. Running yesterday the exhaust from the two RH pipes was not visible, not when idling and not when reving. When idling I noticed some white (with a very slight touch of grey) from the pipe serving cyl 1 and 3. When moving...

Thanks. Went OK I think. Ran it for a couple of hours yesterday, mostly idling. Seemed quite fine. No gasoline leaks, No coolant leaks, Charging well, Smoothly on all 8, oil cooler fans working as they should, coolant circulating as it should, radiator fans starting / stopping as they should...

if I buy another 1UZ I will definitely try, this sounds good to me, a few horsepowers down the drain in return for overdrive is OK, what I would have problem with losing is low end torque the 1UZ bellhouse/gearbox is a much better fit for my transom than the customary Isuzu/Mazda combination I...

CHANGED CYLINDER HEAD: Changed the RH head yesterday, took a while. (and took a couple of days to thoroughly clean the two heads I bought) Was pitch dark when finished, so just started briefly, without coolant, to ascertain that timing was OK - which it was. Ran smoothly on 8. Will tank up...

right, thanks, yes, if I keep below 2400 the consumption, but when I pass 3000 (and upwards) then its brunch and free flow of juice. I have arrangement for wet exhaust, currently not installed, but this is mostly for show and sound, or sound and show if you like, the water is pumped into the...

wow, thanks, wish I had known that before I threw the autobox away could actually comfortably run the autobox in a boat then, without the box jumping up and down between the two highest gears

right, thanks gloverman, enlightening AFR sensors, is that something you stock? where would they be hooked up? hooking up AFR sensors is that something I could do myself? re running rich; I do not have a good grip of my fuel consumption, the only reasonable grip I have is from running a...

since this is about the 1UZ auto gearbox, may I sneak in a related question; can the gearbox be set up so that when the stick is put into 3 or D or whatever it says on the gear console, the gearbox goes to the highest gear and stays there, regardless, until the stick is moved to Neutral position?

Hmm, not sure what AFR is, air flow resistance?, if so - I guess even a minimal turbo would go a long way to sort that out. Anyway, bank perspective, it seems a tad meager to assess the satisfaction of 8 cylinders on the basis of 2 measuring points. Should one do that it would probably mean...

EXHAUST TEMP / TELL TALE OF ENGINE'S WELL BEING ?? In large diesel installations, say 20 000 / 30 000 /40 000 horsepowers and thereabouts. (these are slow reving beasts - say 80-105 rpm) On these installations it is not uncommon to watch the exhaust temperatures as a quick check that the...

noted one small difference between "old" exhaust cams and "new" exhaust cams on the old cams the M6 holes in the sizzler gears are aligned, so that my M6 bolt went into one cogwheel and came out of the other one not so on the new cams, the holes are not aligned and the M6 bolt is just pressed...

done, started snappy, good, now to change of cylinder heads, will take some time, cumbersome to work in a boat
