So, last weekend I towed a 12x6x7 trailer on a 1900 km round trip to NSW and back again. All went well on the way there...
However, while we were there, we went out for a bit of a drive, and due to a lack of traction on a sideways slope, ended up in a sloppy mess which took about 15 minutes to get out of, a fair bit of which was at about 4500 rpm.
After we got out I headed to the car wash and washed her down thoroughly. On the way home I heard what sounded like a bad boost leak, which turned out to be a blown gasket on intake runner #2. I replaced all the intake gaskets with genuine and changed all the oils except engine and gearbox (they didn't have water in them) before we headed home. About 30 minutes out of town I glanced at the temperature gauge, and it was just below the red, so I dropped back to third and ran along at 3500ish rpm for a bit until it returned to about normal again, and when I accelerated back up to 100 km/h and shifted to 4th, up the needle went again, so we limped along to the first shop we came across (probably 5 minutes or so) and bought them out of water bottles which we used to wash out the radiator, which seemed, despite my efforts with the pressure washer, to be blocked with mud. Having done this, we continued on, and the same thing happened, so we pulled in at a farm, where we found a farmer who turned on his bore and let us wash out the radiator. We did this, which got the temperature gauge to sit slightly above normal, where we continued on, the gauge moving between normal to about 3/4 for the next 10 hours or so. On one of the fuel stops, I noticed a few drips of oil underneath the truck, but as it was dark I couldn't see the source. I was a bit concerned, because the oil pressure seemed to be sitting a bit lower on the gauge than it had previously (just below the first mark at idle, about the middle of the gauge at 2500-3000, whereas it had previously (if I remember correctly, this could be purely imagination) sat above the first line, and about at the third line I think. The oil didn't drop on the dipstick though, so I presumed we weren't losing too much and tried not to worry about it.
The day after we got home, I changed the oil and oil filter (was done before we left, probably about 2500 km total on the oil, which was Penrite 15W50 semi-synthetic) with Shell Rimula 15W40, which conforms to JASCO (JACO?) DH-1 which seems to be what the 1HD-T wants. Oil pressure appears to still be a bit lower, on the first mark at idle, although it may not be lower at all - why do you not take account of things like this until something goes wrong? Upon inspection, the oil leaks are twofold - 1 is what I presume to be the rear main, oil coming out where the engine mates to the bellhousing, and the second is at the rear output of the transfer case.
I would like someone to preferably alleviate my fears, or confirm them, that I have stuffed something up somewhere, and should get ready for some major repairs? Am I overthinking this/worrying about nothing? I'm a young guy who's blown my savings on a Land Cruiser, I want to look after it to the best of my ability but, given that this is my first year of work, I am not particularly flush with cash. I have ordered a set of springs to replace the knackered stock springs that she currently sits on. I haven't paid for them yet. Do I spend this on fixing the oil leaks? Does the oil pressure drop (If it is one, could what I describe cause a loss of oil pressure?) suggest BEBs? Do I budget for a rebuild because it's likely I've caused major damage? The conclusion that I want to draw (but fear otherwise) is that the long continual drive, compounded by a heavy load behind and a struggling cooling system caused the oils to thin out a bit, taxing seals that were holding marginally, and making them leak, and my high-rev antics getting out of the puddle pushed a marginal gasket beyond it's limits, and I'm worrying about nothing.
Please help confirm or otherwise my thoughts.
A bit of vehicle info which may be relevant: 10/92 (MY93) HDJ80 manual GXL. Standard boost, fuel, exhaust. 285/75/16 A/Ts Odo reads 294XXX km. Timing belt and water pump were replaced at 270,000. Coolant is clean and green, no change in level throughout the trip. BEBs were subjected to Toyota's 1996 recall and were checked when the timing belt was done and found to be ok, so not replaced. Before we left on the trip, vehicle didn't leak a drop of oil. One thing I will note is that after changing the oil (both times) and the refil, the oil looked sort of greyish, like some of the old oil was left in the sump, so I parked the front higher than the rear the second time around in case this was the case) instead of perfectly clean like an engine with a fresh sump of oil should look. At the second change, the oil was filthy, as in, stain your fingers filthy, after 3000ks max. The first, I didn't really check because I had just got the vehicle and wanted to baseline it. No metal on the sump plug magnet both times.
Look forward to people's replies.
