I Broke Down in the Volvo 740 & Finally Clean the Engine Bay

Diagnosing running issues on Rosalie the Volvo 745 Wagon, some/all of which caused by me. After a quick OBD-1 code check and a closer look I find the issue. Then take to wiping the engine bay by hand with Dasty degreaser which works a treat!

Excellent job you did there and that's how I'd do it, certainly first time round (you can always clean more small spots later). Our Sweede also has some dents in the roof but we left them and only focused on paint damage.

[@BeardedWrencher]

That engine bay detail was absolutely a labor of love. Even on a car that's not a long term owner, you're still going to go the extra mile to keep it in tip-top shape! I have a lot of respect for that. Great video as always! That cleaner is amazing!

[@Involvod]

Thanks buddy! I remember you were looking forward to it!

[@michaelpegasiou4531]

Well done,you got to the bottom of it in the end.

[@Involvod]

Thanks!

[@MrTeabag58]

Our man always gets there in the end ! Being an absolute duffer I always use a biro and masking-tape to label connections when disassembling things.

[@Involvod]

Duffer 😂 That's a good idea mate

I cleaned my volvo 740 engine bay with a pressure washer and soap, very simple and the result was great.

[@iridiumvalkyrie9017]

How do I learn how to safely power wash my engine bay? I am a novice and I was trying some cleaner with a rag and got nowhere. I'm trying to find this Dasty spray but there are so many variants I am lost! Haha Edit: I am in the USA

[@p12jacob]

@@iridiumvalkyrie9017 I removed the battery from my car and then strapped a plastic bag over the alternator. Then after i had cleaned my engine bay i waited about 24 hours with the hood open to make sure the engine bay was dry before i installed the battery again in the car.

Dasty rules for cleaning Redblock engine bays😁👍

[@Involvod]

Definitely!

[@dbt2787]

you've been working like a soldier getting that new block in so I was proper gutted to find out it broke down, but that engine bay is looking nice! I've been watching a lot of your brother's videos too, very satisfying to watch!

[@Involvod]

Thanks, yeah they are a great watch!

[@mortimergladbreath]

Don't be too hard on yourself! I chased a high idle on my 240 for weeks until I discovered that when I had cleaned the throttle body I had somehow folded the gasket upon installation, creating a tiny air leak. I felt adequately foolish yet delighted all at once! She's looking much better!

[@Involvod]

Thanks! Can catch you out can't it! I nearly did that the other when when installing the front timing cover

[@riffwrath6236]

What was the cause for cleaning the throttle body, idle problems ?

[@timbre7999]

Phew! A relief I'm sure, I always label those connectors before unplugging. Doesn't look original of course but if you print them on a modern Dymo labelprinter in black foil / white lettering, it doesn't stand out and looks quite good 🙂

[@Involvod]

Definitely a good idea 👍

[@Bassalicious]

Remember when a commenter said that disconnecting the battery deletes all long term learn data from the ECU? The ECU fighting against whacky data was all I was thinking when she wouldn't fire up in the garage, didn't expect the king lead lol. If it's any consolation that exact screw-up swapping the plugs has been performed by yours truly in the past too :D

[@Involvod]

Haha! That's why I think it took a while to settle down to, the LH2.4 really don't seem to like being messed with

[@Bassalicious]

@@Involvod I mean for all the ECU knew the engine was running super rich in -20°C weather even though it pulled a ton of injector duty cycle already :D

[@kristofferkorneliussen893]

I've done the excact same thing mate x) Glad you sorted it out.

[@mattwelch4025]

Easily the most entertaining video you've done. I really got a couple of laughs out of this one. We've all been there.... great job figuring it all out!

[@Involvod]

Thanks 😃

[@HainjeDAF]

Chasing weird issues can be an extreme pain in the backside. Don't be hard on yourself. Sometimes things get funky and the problem looks utterly something else. And yes, sometimes we make massive mistakes. We're all human aren't we? 🙂 Good on you, that perseverance made you solve it in the end. Great video again. All the best on your moving back to the motherland. 👍🏼👍🏼👍🏼

[@Involvod]

Thanks mate!

[@SimpsonsClassics]

argh mate, what a pain! but you got there in the end thats what matters.

[@Involvod]

Thanks mate!

[@RichieRouge206]

Yoi did a great job fella, you were logical and sorted it really quickly. I remember my first 740 - or more correctly when my grandad owned it before me… it had the B230K engIne and the carb had issues later in life with vapour lock, etc. eventually Volvo actually replaced the carb under warranty. The only other issue we had was the ignition coil started failing intermittently which gave the same sort of symptoms- would start and run fine, only to randomly cut out after say 10 miles.

[@Involvod]

I much prefer carbs but they can definitely have their annoying problems all the same eh!

[@d.jbrickmocs1637]

Glad you found the problem.and dusty is great stuff. Cant stop using it my self😀👍

Thanks Charles!

F'in ell that's a nasty place to break down! Glad you figured it out! And again, wow is that head a quiet one, very nice.

[@Involvod]

Really nice, so is the block, part of me wishes I had've kept the engine 😅

[@Buffalobulltofta]

@@Involvod yeah should swap it for Lili and sell Rosalie with additional slap!

[@Involvod]

@@Buffalobulltofta that's exactly what I wish I had've done!

[@Buffalobulltofta]

@@Involvod yeah oh well, no rush man since its mainly aestetichal. That's a great project further on, build up a nice renovated FK for Lili (if you don't go RHD of course). I'll guess the by the book "smart thing" would be to sell the German cars in Germany for best income and since you get a lot more Volvo for the money in the UK. But that's no fun.

[@Involvod]

@@Buffalobulltofta I definitely thought about it but I'm way too attached to them. From what I hear it's getting tricky to find a decent 240 over there, I've seen a few nice early 7's like Elsa come up for sale cheap recently, but I'm stuck with her anyway after gluing those floor panels in 😄

[@Phiyedough]

They should design the loom so that either the wrong plugs won't reach or if they need to be close they are of differing designs. I also wish they would fit blanking caps to plugs that are not in use on the lower spec. cars,

[@Involvod]

Would have been nice 😃

[@fhwolthuis]

I'm glad it worked out in the end, Sledge. I love it how you make these investigations sound so easy and logical. Kudos to the clean engine bay, I didn't know they sold Dasty in Germany too, it's very popular here in the Netherlands. You can also get Dasty Professional, which is a stronger degreaser.

[@Involvod]

Thanks, I found it on Amazon and there was one in German, one with Dutch on it. It's great stuff isn't it

[@Involvod]

Will look into the Pro one!

[@fhwolthuis]

@@Involvod Great stuff indeed, but when I use it in the kitchen, I always need to wipe it afterwards with some window cleaner to get rid of the stripes which will be left by Dasty. But in an engine bay it will probably be okay 😂

[@Involvod]

@@fhwolthuis especially the engine bay of this particular car 😄

[@ched999uk]

Great that you worked out what was wrong - well done. I like that code flasher thing - I remember building one (trip to Maplins by bus to get bits) for my 850T5 and finding MAF had failed!

[@Involvod]

It's quite cool isn't it! Fortunate to have it on this car, the other 2 all have the same switches and sensors, but no OBD at all! Not looking forward to when either develop running issues 😅

you absolutely 100% sure not the first 1 to make that mistake and probably not the last either. Volvo should have tagged the wiring loom IMO.

[@jackjacko8706]

Plugs can be plugging difficult.

[@corychecketts]

The Lambda light can be such a pain. I spent last week throwing parts at my 240 only to find out that my MAF sensor plug pushed a pin. Insanely frustrating.

[@sebastianbrrrr7372]

What a relief! Man that was hard to watch. Freak-faults, the ever-looming annihilation of days and weeks of work.

[@Involvod]

Haha yeah!

[@andyknight240]

Sounds similar to what’s going on with my car. Every since I cleaned the PCV box, I have had a slight hesitation on acceleration from 0. I’m guessing a vacuum leak somewhere, but I haven’t found it.

[@Bassalicious]

the PCV system can be annoying, that's for sure. If your car doesn't idle any higher than before the work you did it's likely a leak would be between the MAF sensor and the throttle body or less likely between the PCV box and the block. A handy trick to find vacuum leaks is to spay brake cleaner on areas you think there could be a leak and listen for engine RPM changes.

[@Involvod]

I normally use carb or throttle body cleaner (when I can find it) it will drop the revs/kill the motor when you spray into where it's leaking which helps you really pin point it exactly. I find it takes me a bit longer with brake cleaner but definitely does the trick

[@Bassalicious]

@@Involvod Oh cool, didn't know it was faster. Maybe I shouldn't use brake cleaner for everything after all :P

[@mayflowerlash11]

On the timing belt cover there is a little sticker which appears have a timing belt for a twin cam. Did this cover come from a twin cam engine?

[@Involvod]

I think that must be a generic sticker the aftermarket belt manufacturer uses, it's definitely a single cam cover 👍

[@salsolo2403]

easy mistake !

[@MAL-Collector]

You are definitely not a detail guy. That engine bay clean was awfull. Use engine cleaner and spray it all. The use a brush. And pressure washer really close. The spray soap on engine again. And pressure was for last time. Remember to cover you're generator in a plastic bag. And Remove the battery.

[@englishgrandad3298]

Nah have a cup of tea, its fine.
