hey hey

Not familiar with these engines as yet, and will be chasing up a workshop manual shortly, but anyone know off hand- if these are an underbucket shim valve system- so adjusting the valves means measure, calculate shim, cams out etc etc? Heard a little of what sounds like valve train noise mostly when cold, so its going on the list of things to do.....240,000k's and who knows if they have been touched...I know the timing belt has been, but who knows if these have been overlooked....

Also if I do change these over myself, anyone here interested in a write up?

cheers

Pretty sure they are shim-on-bucket like the rest of the A-series...

In saying that, my 7AFE has done 325,000km and as far as I know the valvetrain has never been touched (my dad was the original from-new owner) and it's still nice and tight and quiet. Head has never been taken off either.

definitely shim on top of bucket. clearances can go tight (from valves pounding into seats), or loose from valve stem tip wear and/or shims getting worn centres. fixed hundreds

      Current Oil Specials

      You're not wrong there Ash, greedy retailers trying to make a dollar. I say let them all bleed & see how they like it, surely they must be hurting by now. I have rarely walked into either of the big 3 auto stores, essentially purchased nothing all year. Have plenty stock to keep going, anticipating big Black Friday sales. I have also been considering swapping out my Aurion for something much taller (cos lower back issues) & super efficient but I just can't bring myself to flushing all that $$ for the sake of it, especially given the Aurion is still like a new car. Also concerned about leaving the very good safety of a car manufactured by Toyota for something a little unknown despite also being Japanese made. Then there's the ever changing landscape in the middle east which is excuse enough to instill fear into everyone from producers to stockbrokers to retailers and of course those that live there. Interesting times ahead for sure.

      Advice Please

      Welcome to the forum John, Depending on where you are your best option may be to get your existing alternator checked first to be totally sure that is the issue.The next if unable to find one suitable even on the aftermarket you may have to have that one rebuilt ..That may be your only option..I am sure somewhere there is one suitable but finding it is always the issue. I would get good advice from an AUTO ELECTRICIAN as they will have the inside knowledge of any sources that may able able to help you mate. KAA

      Current Oil Specials

      Times have changed post-COVID and no great bargain oil specials worth mentioning until now. Latest Repco catalogue has 50% discount Penrite Vantage Semi Synthetic 10W-40 Engine Oil 6L - VANSEMI10W40006. $35 for 6 litres is worth considering whether it will be applicable for your vehicle's engine and servicing requirements. Because most of my driving is short distance and as preventative measure against oil sludge, I use a comparatively short oil change interval between 3-6 months. It is a cost benefit decision. I use full synthetic for my long distance road trips. https://www.repco.com.au/oils-fluids/engine-oils-fluids/engine-oil/penrite-vantage-semi-synthetic-10w-40-engine-oil-6l-vansemi10w40006/p/A9611158

      Advice Please

      I have an imported Hiace 200 with the 2.0l 1TR FE petrol, engine. There is a noise from the engine that i'm pretty sure is the alternator. I'm finding it difficult to source a new alternator at a reasonable price, It seems there are plenty for the 2.7 engine. Does anyone know if one of those would fit my 2.l engine. Thanks

      A Greenskin

      Hi Team Toyota, I am fortunate enough to be the proud owner of 2 Toyota's - an '03 Rav4 AWD Cruiser and an '07 Toyota Hiace. Both have been reliable and strong with incredible components that are so well fitted, it's a struggle to dismantle any part of them. I'm modifying my van and will probably have to sell the Rav to complete the project. I will look forward to learning much from you all and wish you all happy and safe motoring. Gidget

      Car Detailing Recommendations

      I recently came across Car Detailing Sydney, and they seem to be a great option for getting your car detailed around the area. I had my friend’s 2020 Camry detailed there, and it turned out fantastic—the shine was like it just rolled off the dealership lot. It cost about $400, and they were really thorough with both the exterior and interior. Definitely worth checking out if you want your Corolla looking fresh again.

      Landcruiser 200 GPS

      I got mine from GTzone, a 7-inch head unit for my 2018 Land Cruiser. I think all the aftermarket Android screens are very similar. My one from GTzone came with a GPS antenna, I believe the one from Brummstadt should include one as well. It has two options for using the navigation app, one is to insert a SIM card or share a hotspot from your phone to use the navigation apps, which uses the built-in GPS antenna, the other is to use the built-in Apple CarPlay system, which uses the phone’s GPS for navigation. In my case, because I always travel to the outback during my vacations, some areas have no signal at all. So, I downloaded offline maps from the Play Store to use for navigation, which doesn’t need internet during navigation and only uses the built-in GPS. It saves your phone’s power at the same time, I guess? So far, it has never failed me, never led me to the wrong roads, or shown me in ridiculous places like driving on a river LOL This is the product I mentioned above from GTzone, in case someone is interested: https://gtzone.com.au/products/toyota-landcruiser-200-series-2016-present-7-inch-wireless-carplay-android-auto-head-unit-navigation-bluetooth-wifi-head-unit
