Hi,

This is my first post here.
I have a boat cruiser with twin 5.7 Volvo 2008 engine (~550hours)
Volvo suggest Synt/SAE30 oil in their engine.

Previous owner switch to Mercruiser 10w30 (mineral) because engine burn oil. This is probably due to a bad breakin.

This summer (2013) I switch it to 25w40 Mecruiser (mineral) oil. (Oh ! we are located in Quebec/Canada, minimum temp is 50degres and Max 85degres during boat season)

There is an oil leak on my main rear seal. I do not want to have it fix since its just 2-3-4 drops per ride. Thats bug me, my engine room is clean like a showroom.

Now my questions;
What do you think If I add "No Leak" stuff in my engine ?( http://www.goldeagle.com/products/productF295.aspx )
My goal is to run her next summer with Valvoline 20w50 HighLife (with noleak additive) Valvoline offer also SAE30 HighLife (do not forget Volvo suggest SAE30).
or I keep my 25w40 mecruiser oil and include a bottle of NoLeak.
There is also possibility to use 10w40 Valvoline HLife.

at the end ;
Both engine are leaking (2-3drops from main rear seal).
Both engines burn oil (bad breakin).
Both engine run A1

What do you think running them with 20w50 Valvoline High life ?

thanks all

LOL

I'd say try the sealer oil first.

Though me, personally, has had good results with Blue Devil Rear Main Sealer (same as oilsealer.) Stuff is great.

However, add-in stop-leaks are generally frowned upon!

Don't add it and fix the seal in the off season. Stop leak is going to affect the performance of the oil and you don't want to sacrifice protection for 2-3 drops savings.

The solution is fix the leak, unless you don't mind replacing the engine later.

I want to try the NoLeak stuff first because fixing a Main rear seal on a boat is very expensive. Mecanic guy has to remove the engine , im talking here about 1500$ for a seal of 25$.

Question 2. What about running her with NoLeak stuff for a small 10hours and then I made an oil change. Since Valvo MaxLife contains noleak additive does it mean its not a good oil?

Boat engines get yanked for rebuilding anyway, I'd wait until then.

Though I wouldn't use a specific sealer, maxlife 20w50 would be okay. Incidentally, what's your typical water temp? Many boats run cooler, like 140'F, and this is "bad" yet accepted.

My thermostat shows around 160degres when engine is hot.

160degres is good with 20w50 ?

or straight SAE30 MaxLife has it should be?

As requested this is one of two 5.7 Volvo engines (320hp). You can see the oil leak under the main rear seal.

He is a long way off for a rebuild, No easy task either yanking these things out.

Hemitom : that's why I want at least try to fix leak with "special stuff".


Is SAE30 same viscosity of 20w50. My web reading teach me that SAE30 will be more thicker cold then 20w50. correct? Since im running engine hot does it mean Ill get more leakage with sae30 then 20w50 ?
