Might have been the OPC then - I had it in for a replacement windscreen back in Feb / March and they did a free car check for me with a condition report.
Leading evidence: 'Use rad seal or eggs in a coolant system' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check me' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I was actually checking on a previous oil leak which was occuring on the left side cylinder head but appears to have dried up now (possibly because I've changed to a more suitable grade oil - 5w40 shell helix ultra).

chalk dust after cleaning the outside of a component will also help you ..
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi Folks!
Been absent for awhile but thought I would poke my head in as I was changing the brake fluid earlier this week and whilst doing so I noticed some greyish white chalky deposit all over the left side cylinder head... from my initial google search results I understand this could be caused by a coolant leak however I haven't had to top-up the coolant from a very long time and the level appears to be bang on the mark in the coolant reservoir.
I was actually checking on a previous oil leak which was occuring on the left side cylinder head but appears to have dried up now (possibly because I've changed to a more suitable grade oil - 5w40 shell helix ultra). So initially I was concerned as I thought it could of been the product of burning or combustion...
Has anyone else had a similar occurence and can offer any insight?
That looks very much like leak detector spray .. it's all over the coil so obviously it has been sprayed on .
we use it to locate hard to find oil leaks with rear mains being the main culprit .
Coolant leaks tend to have a pinkish tone to them and are more chalky .
Hi deMort - hope you are well mate :thumbs:
Hmmm got me thinking now - maybe it does have a slight pinkish tinge to it (I'm colour blind which doesn't help) :floor:
It defnitely wasn't there before the car's MOT earlier this year, could the MOT tester have done this? Didn't go to my usual MOT place but this wasn't the only issue I had at the last place (if it was them)
Any good way to remove it?
Can you supply a link to a product - I have a gearbox leak on a different make of car that might be the speedo seal or output shaft seal or aluminium porosity
Young man .. it's always a pleasure to chat .
Image below and i've marked areas .. that is over spray in a sense or leak detector spray ... i've not used it since i left OPC so 5 years but that's what it looks like to me .. either way someone has sprayed something over the coil .
A coolant leak .. if pink then antifreeze has a very chalking pink look to it .. you also have to consider .. what's in that area that could be leaking to cause this ?
Pink antifreeze .. it has a sealant property to it .. kinda like we used rad seal or eggs in a coolant system to stop a leak .. it will in a sense coagulate on a leak and stop it .
If nothing coolant related in that area then it kinda rules that out .
It will be obvious on a pipe though .. a build up of chalky white powder on the joint .
If the car is white then a respray and its over spray .. to me though ..
It looks like oil detector spray .. hence that's what i think lol .
There are many different types of oil leak detector from dyes to spray on additives.. just do a search .. engine oil leak detector .. you'll soon find something you can use ... chalk dust after cleaning the outside of a component will also help you .. talc powder if your not near the south coast where we have plenty of chalk lol .
Awesome thanks deMort :thumbs:
